I have a guitar that likes La Bella Criterions better than anything else, but it usually gets a set of Martins because that's what I can get locally. If you've got a guitar with a tender front or a high action, I'd recommend La Bella Silk and Steel. If you want a set to last for years, I have found Gibson Mona metal strings very durable (but a bit dead to start with). Rotosound are my favourites for electrics.
