My main complaint about Les Pauls is that they are not too ergonomic. They don't balance quite right on your lap, they're heavy, the angles are weird, and the body shape is not too comfortable when it's pressed against you. It was one of the first electric guitars (I think?), so the design problems are maybe not too surprising.
Once you play them all the time I'm sure it would be fine. But I'd go for something more modern and comfortable.
I always rave about my PRS SE-24. It was cheap and is super versatile for everything from metal to country.
