Briggs 22hp. The Briggs engine is the only thing I have hesitations about.
Why ?
Briggs make over a million engines a year and have been doing it for quite some time.
I prefer Kohlers but only because they are easier to work on and in particular the cowel comes off a lot quicker.
Honda was the last of the top shelf engine makers to exit the market because there was no profit in it and the rest are all fairly well so so.
Some are marginally better than others but none are particularly good nor particularly bad and they all have problems, I fix them daily.
No mower company is going to deliberately fit garbage engines to their mowers or they won't be in business next season.
It is a different world now.
With the internet and social media you can not pretend a problem does not exist as you could have done in the past and gotten away with.
The only thing I would be wary of is any Chinese engine that has no independent representation as there is no guarantee that parts will be available next year.
