The best pet i have ever had was a draik. i never trained any of my pets. i was just one of those people that just rs and sniped.
A few years back I had bought a krawk transmog and tyrainian paint brush (back when krawks still looked like this http://images.neopets.com/pets/happy/kr ... n_baby.gif), and he had 85 in all stats, with a really good bd set. Some noob managed to get on my account, took all my money, and pounded my krawk.
My "best" pet right now, BD-wise, isn't very good (a good lab rat I received with untrainable stats; upping his level now), but I did doublepaint an awesome pet yesterday. =) (Faerie/Royalgirl) Current goal is a Royalboy Draik...
