You will unlock a fifth talent at mega. Training to mega is definitely worth it on a good pet.
As for Ultra, that's a whole different story. No additional talents are revealed, stats are not changed, not even an additional socket opens. It's a ton of work for no reward. There is no reason to train any pet that high UNLESS you have an "ultra" gem that is so spectacular that you can't imagine your life without it.
Unless you're doing it to socket the best ultra gem ever, training to ultra is an utter waste of time, energy and pet snacks.
Should i level my pet to ultra? Idk if stats increase, but i do know that no more talents can be unlocked. Tell me if pet stats increase at mega.
Stats on your pet never change, they just fill up as you train your pet As for going to Ultra, you only need to do that if you want to use an ultra level jewel, such as a dealer or sniper.
If you are confusing stats with talents, your pet will get talents up until mega for a total of 5, no new talents are unlocked at ultra.

the stats don't increase but certain pet jewels require the pet to at ultra such as spell proof or the dealer jewels. I also believe you are gifted a jewel at ultra but I don't know much about that.
you should train your pet until ultra, but if you get a new pet with around the same pedigree or higher pedigree or has skills that has a high average rarity, you should leave your other pet (unless it isn't mega) and work on your new pet.

Pedigree isn't a good indication of usefulness. Some desired talents are uncommon or rare (Fairy, school giver, spell defy) and some ultra-rare and uncommon talents are generally unwanted (cards, selfish).
Training to Ultra would be a waste in any case except to add a high rank jewel.
