If it’s that easy for you and you get good results then simply go for it. Many third party tools provide a better workflow, faster results, different vibe, whatever. I use and enjoy a lot of UAD, SKnote and Slate Digital plugins. Haven’t used Alloy 2, the product video definately looks cool. Don’t miss the freebies I mentioned.
But as many tools as you have, they are only as good as the one using them. Just get to know the interestings things in detail.
