Lots of options. There is no best. What works for me, or others here, may not for you. There is a list for a reason - he makes great products. If there wasn't a list and he asked you to wait 2 to 3 months then I'd worry. Be that has it may I'm similar to the person above who commented on the skimmer. I purchased one back in 2000 and I'm still using it today. I even called to ask if it was worth buying a new one. He said no. Same thing only a few small changes that have nothing to do with the skimming performance. He could have sold me a knew one but instead was honest and said to save the money.
I said cool. Called him a month later and asked about a sump and he said sure. So I bought the sump and waited. Good quality which is what I expected. Packaged very well such that it could withstand silly shipping hand or a low yield nuke. My point is that his products work for me and work well. I also like to support small businesses / family owned. I know there are probably other sumps or skimmers that will work just as well, or maybe even better, but this is what I went with.
TL;DR - there is no best. Make a list of options you must have, then a list of options that would be nice but not mission critical. Then look at your growth (upgrade future). Lastly, your budget. Then make a decision.
