The clipper is a fine ship and does a lot of things well but it needs a lot of work to be able to properly compete with other multi-role ships. It cannot carry as much as the python despite being bigger, it's faster but nowhere near as survivable, and it's hard point placement is among the worst in the entire game. I'm not saying that it's unplayable or anything like that and I'm not saying that you shouldn't enjoy flying it but just because you enjoy using it does not mean that it's a good ship compared to others that are available. Because it's not.Clipper is one of the best all round ships in the game. Versatile, good at many roles, nice SC manouverability for its size, and very fast.
No idea why people keep banging on about it needing to be better. If it was any better then there would be threads saying how everyone is flying a Clipper and how other ships need a buff.
You basically end up in a never ending circle of buffs to other ships to overcome the current favourites.
The Anaconda is a good ship, but it has its weakneses. For example, while having the largest jump range, its otherwise a terrible exploration ship. It makes a good combat ship, but its also a large slow target.
As for what you said about the anaconda you could say the same stuff about the Cutter or the Corvette. The thing is that the Corvette and the Cutter are locked behind rather large rank grinds and neither are as versatile as the Anaconda. And neither can match the anaconda for its jump range or even come close actually.
