Advice Needed On how to Pick out a Toilet. Seriously.

This is the kind of thing I would of posted on the old deals, so I figure maybe some of the same knowledgeable folk could help here.
Who knew that buying a new commode was so complicated ?

I need to replace an early low flow model that clogs if anything other than liquid goes down it. I'm having floor replaced in this BR so a good time to do this.
Needs:
I need a higher (aka comfort ) seat for a senior.
I want one that will flush and be water friendly.
Quality/ reliable manufacturing. AKS no leaks.

I have been told that Home Depot has seconds or less than quality items. They might be made by the same people that make ones you get from a pro and look the same, but are not the same item. Is this true ?
Where do I find one ? What do I look for ?

I'm frugal as opposed to cheap. I don't want the most inexpensive. Those won't work well.
I want the best bang for my buck.

Any one able to help.
