I doubt you’re older than I am but if you’re happy in your current job, then that’s awesome, dude! Congrats!
Regarding technical aspects, technical aspects is a tricky term because it makes it seem like there’s an industry standard when there isn’t. It’s why my advice and that of @gouashua basically come down to use what you like.
So if you’re the boss, if you’re in charge of making decisions, I’d look at: needs of the platform or market you’re serving, your personal needs, software that fill those needs, and personal preference, in that order.
It comes down to personal preference again because ALL professional software come with the same basic functions, they’re just handled in different ways. So things like ultra high resolution, exporting and importing image and videos files, importing sound clips, etc are all pretty standard options these days,especially if you’re looking to more traditional style of animation and less cutout styles… It’s just a question of what feels more natural to you which usually comes down to what you trained on.
On the other hand, if you’re not the one in charge of making decisions, well the decision has already been made for you
Software the last thing animators should worry about, imho. It’s like asking what car should you buy. Y’know? It’s a difficult question for others to answer. Even comparing different specs doesn’t necessarily mean anything without knowing who the buyer is or what they need. Having a racecar would be hell for a pizza delivery guy because of gas, maintenance, and monthly payments alone.
On the other hand, if he already had the race car, it wouldn’t make sense for him to switch to a pickup.
