J tech Laser 2.8w or 3.8w and why

Ready to order the laser kit for my x-carve but only finding information and videos on the 2.8. I figure better to buy the 3.8 even though the 2.8 seems to do what I want to do with it so my question is what would be the major differences other than faster cutting time? can the 3.8 do everything a 2.8 could and more or will there be limits on the 3.8 that the 2.8 would do better? I am new to laser engraving and want to make sure I do not buy the 2.8 and need to upgrade later or waste more money …
