I own 2 jackson guitars and have owned a fender in the past. i found that fender was a very versitile guitar and had great tones, but if you want a guitar that is pretty much built for playing metal, then go with jackson. they're also very affordable if you find the right model. the dinky models are well priced. as for gibsons, they are amazing instruments but they're charging alot more for them nowadays. if gibson was a prime chice for you take a step down and settle for epiphone which is still a wicked ax.

buying guitars is avery touchy subject. i also recommend just trying as many different guitars as you can until you find one that feels right for you.
