I use regular Pokeballs because that's all I can afford. The only time I've used Ultra Balls was during the Mew event.
I just use regular pokeballs. I caught a Registeel with just one, and I've heard of a lot of people wasting a ton of ultra balls on a Pokémon that I caught with fewer pokeballs, so I'd rather just try my luck with the cheaper pokeballs.
I find myself not buying Great Balls anymore, only Pokeballs and Ultras XD With Pokeballs, if I have overwhelming numbers, SOMETHING should stick, and Ultra Balls are just better than Great Balls
Yeah, I'm going the same route as Wolf here. I'd much rather use cheap Pokeballs to catch things than waste my PP on Great and Ultra Balls only to burn through them. :\
... Heeeh I forgot about the other balls' existence XD I only get regular and I have two Master balls rn.
I limit myself to regular Pokeballs, because they're cheap and when I've used Great/Ultra balls in the past I haven't noticed much of a difference in their success rate...and it feels bad to burn through them when they cost more. xD
I use regular pokeballs for eggs/fossils and first evolution Pokémon that should be fairly easy to catch. For most other Pokémon, I use great balls, unless it's a legendary, in which case I'll jump right to the ultra balls.
