English= Taiwan
Less Bugs and other things= Hong Kong
more players on TW cuz of the amount of E players. But if you want to play TW go ch4 thats english Channel. Server 2 tho
u CAN just run gamebooster and u get less lag or try WTFast or possible use them both at the same time o.O
U may lag less with these but u most likely will lag in Highly populated places like Korin City
Well, as I've noticed... you deal more (overall) damage on TW, there are more -foreigners- on TW. I wouldn't say they're "English", but most understand the language well enough to have a conversation with you. If there is a bug on one version, its been on all of them. There really is no "best" among the versions, it all depends on your preferences. If you would really like to know, then try both out for a month or so and choose which version you would like to play long-term, or you can play both. Up to you, really.
HK is full of foreign player just need to look for them ... and HK is way more active than HK except when all the chineze players are sleeping and that lasts for 3 or 4 hours not longer
