I got the cutter first, loved it, main ship I fly in.
Then I did the corvette rank up, bought it, got it properly engineered and intended to make it my main ship.
Funny thing, I found I was just opting not to use it, I'd jump in the DBX or exploraconda to get anywhere quick, and the courier for fun high speed stuff. I was using the corvette for blowing things up but I didn't want to use it for anything else.
After a while i realised that the cutter could do everything better, more jump range, better shields, better cargo space, that awesome boost speed and ramming ability, and of course, it still kills things as easily as the vette (as in, destroy an npc conda in 60 seconds with the cutter or 50 seconds in the vette), the slight combat advantage of the vette was totally outclassed by the Shields and boost speed of the cutter.
So the corvette is currently retried to the garage, I go everywhere in the cutter again, and it's fun, sure it drifts like crazy and takes a year to come to a full stop, but it feels more like a huge fleet command ship than the corvette.
I'm hoping one day I'll find a good use for the corvette as it's a great ship too, maybe it'll turn out to be a thargoid interceptor, or get a buff in the jump range.
Is it worth the time it takes to get either of them? Definitely, they're great ships, different from the conda, I prefer the cutter, though others prefer the corvette, there's not a huge deal between them, but keep at it and enjoy whichever you get
