Differences at 5/10 between Prima and Party

[kapw7]

I've been playing at Prima for the last month as they made me an offer I couldn't refuse. I've been playing 3/6 and tried also lately the 5/10 games. They look pretty tough but I guess there are always the bad players/donators depending on the time of the day.

So my question is how these compare to Party 5/10 SH. I'm sure that table selection is much better but is Party so much better that someone can achieve a 1 BB increase in winrate by moving from Prima to Party (5/10 SH)?

Cheers
