That hasn't been my home game experience, but everything is group dependent. Most home games I've played have been .25/.50 and .50/1, where 3x is standard and 10x is a typical 3-bet. I think 200BB entry on microstakes combined with a general demeanor of always wanting to see the flop is simply too deep and loose for my taste in general. But I'm in a smaller town where there aren't a lot of games going on it seems.
If you raise to 6x preflop, there's typically comments of "geez, quite the big raise", and some seem slightly peeved they can't cheaply see the flop. So it requires a 5-6x to isolate with strong hands, but it also leads to being seen as way too aggressive and playing over the stakes in this group. So its an odd balance between wanting to play poker and just going with the group flow to have fun and be social.
With $20 buy-ins and microstakes, .10/.20 (or .25/.25 if your lowest chips are quarters) would be the right stakes for more "serious/proper" play, as least for my group. 100BB isn't just a round number, it seems a fairly magical starting stack size to regulate looseness of the game in my experience.
IMHO, if you already have a group you play with and want a more "serious" game, the game should be set based on a buy-in size that the average player in your game would be bummed to lose 2-3 of but it wouldn't hurt them, and tripling up would be fun but not change their week. Whatever that stake is for your group, make that the buy-in, and then set blinds to have 100BB based off that buyin.
