My personal opinion is that Arb blockchain it the best speed on chain I ever experienced. 
Low transactions, arriving time - fantastic, I like it and I use it every day!

It is definitelly strong… among optimistic rollups. But soon such projects as Scroll/zkSync/Starknet/Taiko and others come with their zk EVm technologies and there will be no point in optimistic rollups i guess, so i don’t quite understand what they will do in future

Optimistic rollups will always be cheaper and more flexible than ZKs. Don’t fall into the trap of comparing present-day optimistic systems against future ZKs.
