lol I feel like you answered your own question. um, all I can say is reread the reviews. I know that what I gathered was that it heated up super quick and it was incredibly uncomfortable or down right painful for some.

The Siri has 31 reviews up, 20 of which give it 5 stars, 8 give it 4 stars, and only 3 go lower. That seems pretty positive to me. Though truly, you're not really going to get a better answer to your questions than from the reviews themselves.

to answer your title question, different things for different people, honestly for something as personal as this that's the best you can get sometimes, I for one love my siri, and desperatly wish it were waterproof, however I also wish that I could turn a base speaker into a vibator so that's probably why I love it so much. it really seems to depend on how you rate your vrooms, there are diferences in strength and differences in pitch(not sure if that's the right word but it's the best I can come up with), all of mine, the siri, sinfonia, and a generic jelly vibrator, have about the same strength which is as far as I gather decently strong, however the siri is by far the deepest/thuddiest(I'm gonna use that as a word) with the generic being the buzziest. and though my sinfonia is a great toy, I hate it, and if I had thought before buying I would have known that but aside from functional deffects I think the most common reason for mixed reviews is just different wants.

however on to your other questions, to my knowledge the siri has the same motor as the liv and gigi, i'm not sure about the mona. I've never had an issue with my siri heating up, even remotely and thats with an hour on high without space too cool down so I think in that respect it's amazing, it charges wonderfuly, confused me at first but we've gotten over that,
