After trying out a few perps, I have to say the fee differences are quite noticeable.

But when actually trading,
I found that coins with fee differences don't have very high liquidity,
For larger positions,
The direct loss caused by the spread is really hard to ignore.

Also, I noticed that some perps only have market and limit order modes,
There are no other order modes available,
The experience is not very satisfying.
