So just to toss my 2 cents into the ring on the 2.
I've been here for quite a long time and will be for my eq career. I can say I've never had an issue with the marketplace here, but have many times on rg. As for the compile it self having zone/warp/summon corpse are awesome benefits. The bot plugin serves it's purpose and works good enough for me. I've never not been able to find help or a macro or anything I've needed in all the time I've been here. Rg imo has a more active community but the one here is way more reliable in my experience and more knowledgeable.
Lot of ramble but I think once you get setup here you won't go back. They may have a more active community but I'd take 1 person that actually can help me over 100 that just babble on in the forums.
Just my 2 cents. Enjoy your time here! I'm no coder but if you have any questions feel free to reach out.
