In reply to bigdelboy: I have a Boardman CX now, but had a Felt hybrid for about five year before and did something like 10,000 kms on it. Both cost about the same amount. So the CX is definitely a bit faster (same tyres, same route) I reckon just because of the aero dynamic position - maybe 2 or 3 kmph faster for the same effort? CX races are also a lot of fun if you have a local not too serious series you can join.
Something in favour of the hybrid though, mine had better brakes - hydraulic discs, the CX has cable discs which are frankly a hassle and don't work as well. The best brakes is obviously important for urban riding. If you are coming from MTBs also, the flat bar position is familiar and you'll find it easy to move the bike around on rough ground. I've also started doing some bikepacking, and strapping gear to the flat handlebars is much easier than on the drop bars of the CX.
Both are really practical bikes; CX is kinda trendy now I suppose, but I wouldn't write of a modern well designed hybrid - but don't get one with suspension I reckon. If you need suspension you should be on your MTB!
