I don't mean to sound like a complete prick, but both those guns are Terribad, you might be lucky and have them running for a while but they are made by companies who have really low quality control.
Some people say systema or die or what not, they aren't great either, they still break down, and ESP if your new and spend 1.8k on one and have them break on you within a few months, trust me, I know this I have 2 friends who both got PTWs as their first guns.
Brands like Tokyo marui aren't too common in country but they are deffinately something to consider, their guns are quite cheap, and their quality is outstanding.
Google G&P and King Arms. Reputable brands, great quality for the price range, and don't need much out of box tuning
