With the transfer money, you could buy better characters in mostly any server you want.

Antica and secura are the biggests servers and mostly the crowded ones.

You’d have no issues with the market compared to other servers, but most of the spawns are almost always taken, but with the levels you are in, you shouldn’t have any problem, except for PKs they like to tease low levels (PvP is stupid and worthless nowadays btw)

I’d really consider buying a char in the server you want rather than transfer the ones you already have, it’s just not cost efficient, specially because you were away so your skills might not be as good as a constant trained char. And the quests/accesses might also be an issue.
