Tiller steering, most people sit on the side tube which is safe in most reasonable conditions.
Console adds weight, sacrifices foldability, but probably improves your ability to handle the boat at high speed. Console may be safer for the pilot who is less likely to fall overboard than sitting on the tube.
I have spent a lot of time on RIBs with consoles and they are great fun. I have spent a lot of time on inflatables up to about (from memory) 4.5 or 5 metres with tiller steering.
A small boat with a console does one thing very well. A small boat with tiller steering is more spacious and versatile.
Personally, I think a tiller is all part of the "boatiness" of a boat.
It boils down to priorities and tastes. If I ever bought a big boat, I would consider a console. For a small boat, never.
