Sounds like a tough decision. I don't think you'll go wrong with either boat, but I'm still partial to the 190
I, too, had to start parking outside when we got the boat. I still make room for the wifes vehicle in the garage though, so that's a plus (for her I suppose). Here's what it looks like after I've "packed it in" for the week after boating all weekend. Most of my "garage stuff" gets packed around/under it so we can still get the other car in there.

I can't comment on the handling between the larger and smaller boats, however I CAN say that this Yamaha rides 200% nicer than my '98 Rinker did. They had similar deadrise (the angle at the transom of the boat) measurements, and the Rinker was about 750lbs heavier than the Yamaha. The Yamaha rides FANTASTIC in lake chop. Even very windy days on a relatively shallow lake still gets me an acceptably smooth and dry ride. I have to really get into some bad weather to get an uncomfortable ride. I would expect the larger boat to handle just as good or better in terms of comfort of ride. Again, I have little experience with the larger Yamaha's.
Storage space on the 190's is AMAZING. The rear compartments are literally cavernous. I'm 6'2" tall and 215lbs, and can easily fit my entire body in there and have the seat closed above me. I was all the way in the port forward compartment this past weekend running new stereo remote wires. I can get 6 adults, with 3 beach bags, 6 towels, and 2 large coolers on the boat and not have anything out on the deck. I also keep the wakeskate, tube, and big disc on the boat all the time, as well as our floaties, kids toys, safety gear, bumpers, lines, etc on the boat all the time. I've never had a hard time fitting everything that needs to go with us on the boat. Even with 4 adults 4 kids on the water for a day, storage is never an issue.
For me, the 190 is the way to go. Mods to make it your own are always better than someone else mods. Also, the lighter tow will be a blessing in disguise once you have the SUV loaded up with women headed to the lake for a day, even more so on the way home when everyone is sunburnt and has the start of a hangover already, and wants the A/C on


. Nothing worse than having to stop and let the tow vehicle cool off on the way home, ask me how I know
