Handheld torches, go new gen. HID only. Pretty good battery life, better sealing and they are pretty compact now, the days of bulky Ikelites are pretty much over.
Cable torches, specialist items only IMO now. The cable is a weak point, prone to leakage and getting tangled in stuff.
There is such a big variety of torches it's hard to say 'buy x and not y' as y might suit you better than x does me. Best to go track some down 'in the wild' and try them out and make up your own mind on the subject!
