Asking for Painless, Well Detailed and Fitting is the Holy Grail of modeling! LOL You can get any two, but not all three!
Well, that's not exactly true, but it's close. Tamiya has great fit and is relatively painless, but isn't always the most detailed or accurate. Dragon is well detailed and fits, but sometimes causes great pain (especially trying to figure out their instructions!). I've not built up any MiGs yet, so can't comment on anybody's kit for those. You're pretty safe with Tamiya, Dragon and Hasegawa these days.
What I've found is that the kit itself is not the answer. The skills in your own hands is. Grab a kit and start building, work slowly and carefully, and do lots of research if accuracy is your bag and you'll do fine.
