The 630 is a pretty nice machine, it's well liked by many. Your setup looks pretty nice, and should work well for nearly anything you'll want to do on a 68k. Hell, the 6200 and 6300 are nice enough, if that's what you can get your hands on.
One of the important things to remember today in 2016 (context!) when almost any old Mac is going to be available relatively inexpensively is that most of these worst Mac lists (both the liked one, and LEM's new-ishly renamed "Compromised Macs" list were written in a time when an old PowerPC Mac (like, early beige stuff) could still cost hundreds of dollars.
If you were going to pay $300-500 for either a 6200 or a 7200 and use it as your main computer, the advice to go for the 7200 or even a 6100/7100/8100 makes a fair amoutn of sense, really. Today, if you're getting them for free or nearly free, it doesn't make a whole lot of sense to discriminate, especially since, you know, you're not paying hundreds of dollars for them and using them as your main computer.
The irony in all of this is that the IDE probably makes the 630 and 580 much better machines for use today in modern and preservation contexts, especially if yourh'e going to max the ram. It doesn't help all of the actual technical problems the 6200 and its bretheren have, but let's be real, there's a goodly sized contingent of people online buying these things to connect them to cheap-old LCD monitors and play Oregon Trail and similar games on them. For that task, (and even for what they cost when new) they're not bad machines.
