I used to cut a lot of steel and aly section, started off with a bandsaw but moved on to the cut off saw, would definitely say the cut off saw. Bandsaw was very slow and the cuts were not as accurate as the cut off, just need to be aware that the cut off saw produces a lot of swarf and plenty of sparks if cutting steel although the blades with teeth produce less sparks than the grinding wheel type. Would also choose the Bosch brand over sealey any day. I have also used the Fury saw, a capable machine for the money although a bit 'light weight'. Dewalt also make good machines but are not cheap but then again my dewalt sliding mitre saw has been going for over 15 years without a problem.
