I usually just ignore people who say JPOG is better. Cause the idea that JPOG is a better game than this is just ridiculous. Herding and sleeping does not make a game good. This game blows JPOG out of the water. While it is similar in some aspects this game is not JPOG, it is a vast improvement though. JPOG was only popular cause it was the only Dinosaur zoo management game on the market with the JP license attached to it. Take away the JP name, theme and Dinosaurs and all you have is a mediocre management sim that was outdone by games that came before and after it. It's only people's bad case of nostalgia glasses and fanboyism that makes many people say JPOG is a better game. Usually the people that call this game shallow will then say JPOG is a better game for whatever reason. JPOG was a shallow game. It was terrible. JPOG is garbage. It was garbage in 2003 and it's garbage now. With JWE available as an alternative it looks even worse now.
But I will list some things that make it worse. I will start off with the first issue, management. JPOG was severely lacking any kind of real management. JWE gives players the management experience JPOG never did. Even just refilling the feeders adds management to the game and makes it feel like you are running a park full of actual living Dinosaurs. The food depletes and needs to be refilled. Since feeding the animals was talked about in the books this adds another level of immersion to the game that sleeping and herding just doesn't add, at least not in the same way. Having to cure your Dinosaurs of illness is another level of management that immerses you in the game world and helps the Dinosaurs feel alive. They get sick like any living animal would. Caring for the health of the Dinosaurs was also mentioned in both novels. So this adds to the feeling that you are running your own park. Sure you could cure illnesses in the Dinosaurs in JPOG but it never felt right, it wasn't fun. Keeping the animals fed and curing illness is something that would be done in any modern day park that has live animals. Getting to do all this in the 1993 JP Jeep just makes it so much better.
Graphics wise this game completely destroys JPOG. Even with the animation and AI problems this game is still vastly superior. Of course it's a modern game so it should. The Dinosaurs in JPOG never looked right. They moved like robots. People say the animation in this game is janky or whatever else but JPOG's animations were pretty bad. I would even say bad for a game in 2003, it definitely didn't look as good for 2003 game either. People criticize the attack/death animations for park guests in this game well JPOG wasn't much better. The park guests in that game would jut stand there and tremble in fear till they got eaten. I believe they might have also ran away. The JWE animations are pretty good for what is there. The AI in JPOG wasn't all that great either. As MrGoodBytes said some Dinosaurs had a tendency to die of starvation and or thirst. Another issue is that they would all pile up into I believe it was the Southwest corner of the island. This was fixed on PC with a fan made fix.
On the topic of graphics the Dinosaurs in this game look great. The same can't be said for a lot of JPOG's Dinosaurs. JPOG had a pretty big disparity when it came how Dinosaurs looked. Some would look good while others didn't look that great. One example is the Dryosaurs and the Gallimimus. The Dryosaurs looked better while the Gallimimus was bigger and looked worse. There were other Dinosaurs with this issue. It was like some of the developers put more effort into certain Dinosaur models than they did for others. You don't see this in JWE. All the Dinosaurs look fantastic. You can see they were all made with the same level of care and detail. Even if some of them share the same animations. They all look good and I think that's way more important.
One of the criticisms that JPOG fans use to trash JWE with is that JPOG had mods. While JPOG had mods a lot of the mods were garbage. There were very few that actually did much for the game. Most centered around editing the games ini file will allowed you to change things like the population cap for the Dinosaurs, the amount of fencing, buildings and paths you could have on an island. Matter of fact JPOG was the first PC game that I had ever modded, it was also simple once you did it a few times. But consoles players couldn't do this. They were stuck with a game with some severe limitations. Also if you weren't good with computers you were also stuck with the console limitations. JWE doesn't have any of these limitations. It does have limits as BestInSlot has shown but they are far greater than JPOG's limitations. I would say consoles should have about the same level of limitations or maybe a bit less.
JWE will be supported with updates/fixes and content. JPOG never had this level of support. It only got support from fans and even then that was only for the PC version. As I said above a lot of the mods for JPOG were not very good. JWE will get professional content and fixes made by Frontier. We really won't have to depend on amateurs to fix issues with the game or make content for it. IMO this is a huge plus for JWE. Sure it lacks mod support now but it might get it in the future. The world is a different place than it was in 2003 though so people are more protective of their intellectual property now.
But the really great thing that JWE has that JPOG didn't? The 1993 JP Jeep.

It makes JWE so much better.
