How Pattaya is different from Bangkok?

[infoarmor]

So if you come for meeting boys, the best choice is BKK?

I guess it all depends if you're looking for paid or free time with guys. As I still don't have to pay to have a Thai guy come into my room, I prefer BKK many times over Pattaya. not only the number of guys available on apps or clubs is much higher, but in my opinion, so is the quality.
I've only been to Pattaya once, and even though I got a good number of guys for free, found most of them lacking English skills, some just preferred crashing at your place for the night instead of their bed and even physically, some looked almost malnourished.

A lot of guys in BKK not only have stunning bodies, but are educated, speak good English and make enough that they come to meet you, just because they are feeling like doing it and you can actually hold a decent conversation on many subjects before/after sex.
Plus, there are so many things to do in BKK. Great restaurants, parks, temples, museums, shopping, etc. But as you see in the comments, it all depends on what you are looking for and also I would say also how much time you plan to spend in one place.
