I think the 'regular' style toilet tanks only require more frequent maintenance because they're inexpensive and people use crappy home store parts in them. You can buy five regular old toilets for the price of that wall-mount Toto.
My policy is to use high quality parts in the tank and I've found it pays dividends -- it's been years since I've had to do any maintenance on any of our toilets aside from cleaning.
I'm almost 40 and so far there has been only once in my life I had to do maintenance on a toilet, and I've always had "regular" ones. It was to replace a gasket.
