We recently had to replace an old 1-piece in Pebbles house because it leaked waer.
Saw the lineup of all the brands at Lowes, ended up picking the Jacuzzi brand (I didn't even know they made toilets).

Pros:
Ease of installation
Quality hardware...the toilet tank bolts (common place for leaks) have newer shaped rubber gaskets and seals which look like they were engineered to prevent leaks in the long-run.
Quality and style - we got an elongated bowl highline toilet (good if there older folks living with you) The look and richness of the design is apparent, from the ritzy flush handle down to the design of the top tank.

Cons:
None that I can think of so far.



********
Etc....
Toilets that I hate to work with or replace things on...Kohler hands down, proprietary hardware in some models, and IMO not great as far as long-lasting.
