I should of gotten the larger unit because first, I could power more than 10 kw with my 4310, also I have electric stove and electric dryer. even though as long as I don't try to run both at the same time I could use one or the other, But even running one of those big power consumers, I would have to closely watch all the other loads. 5 people in the house, couple of small electric heaters etc. Also like was mentioned in another pto generator thread the flywheel effect of the larger than needed generator plus the thermo buffer as well. Also probably would be easier to sell a 15-16 kw pto genny than the 10, if you ever needed /wanted to sell it.
I got the capacitor regulated, thought it would be simpler, less to go wrong. But I don't have enough experience to recommend one or the other. I'm pretty sure they sell more of the AVR units, it's supposed to be an advancement over the old style capacitors.
Look into their 3pt carrier, a great option. I modded it to fit imatch QH
