GG poker 5NL or 10NL?

I am getting ready to start playing cash games on GG beyond 2NL. I am playing 2NL to work through their cash tokens that I am getting from clearing their sign up bonuses.

I'm finding 2NL is extremely nitty at many tables during the week, even though there are supposedly a lot of players on the site at these limits. Will try to exploit this but it's extremely tedious just getting walks for anything that I want to play rather than harvesting post-flop mistakes.

For anyone with experience in cash games on GG:

As I am getting closer to moving up stakes, is there any benefit to trying to do 5NL first or should I just go ahead and do 10NL? bankroll is not going to be an issue.

You are not new to poker, so if bankroll is not an issue, then maybe 10NL? The two limits often play somewhat similar, but of course swings will be bigger at 10NL measured in $.
