I play all metal and i need to know which Ibanez would be best for me (AR200 or ARX300) so if anyone could give me a bit of direction that d be great

If you mean AR200 from the 90s, then I'd pick it over the modern ARX - more controls at your hand, and straight out better quality (If I'm not mistaken, they were made in Japan).

Pickups are something you'd want to swap in either model to give it a metal sound, but they have the means to attain an LP-esque tone without much effort.
