I think the answer lies in the quality of the breaker switch, not whether it is thermal push button, thermal/magnetic switch, or solid state switch. Any switch can cause problems if they are poorly made. You can buy a light switch at Home Depot for less than a dollar, and replace it in a couple of years. I choose the $3 dollar switches, which in my opinion are better quality and will last.
My Onan Homesite has the push button breaker in the panel, as does the breaker panel in my G3 boat. Some would say that I paid too much for the Homesite because of the Onan brand, when compared to other Chinese made generators-but it is a well built generator and has served me well with no problems. Others would say that I paid too much for my G3 Eagle 175PF, when compared to a similarly equipped BassTracker-but I believe it is a better made boat and will be used by my kids and grandkids long after I'm gone.
How well a product is made is the number 1 factor in whether I buy or not buy the product.
