Were I to buy again, I'd get an LG pair. Both machines have true steam generators (as do their dishwashers). The only real disappointment with my Frigidaire pair is that the 'steam' is passive. Washer: It heats the water in the tub during tumbling, then dumps in a burst of cold water occasionally, which, naturally, creates a tiny bit of steam that lasts about 10 seconds. It's a joke, really. Selecting the steam option adds 20 minutes to the wash tumble. I think any enhanced cleaning happens because of that, and not because of the 'steam'.

Dryer:  The drum heats for awhile, then a very fine, pressurized mist of cold water is blown in.  Again, it creates little true steam.  Having said that, the Steam Refresh (15-minute) cycle works well in removing wrinkles from pants and shirts.  I use it all the time on dress pants, which don't need washing every day, but do need wrinkles removed.  I also use the steam option on regular cycles with shirts/dress clothes, as items emerge with fewer, and smaller, wrinkles. 

The TOL Frigidaire pair cost me $1850 (before state and local rebates), compared to the TOL LG pair, which would be around $3000.  But had I been able to afford it at the time, I'd have gone with LG.

As for the drum size, I say go for it!  However, problems arise when you try to cram all that clothing into the dryer, whose drums seem to have maxed-out at around 7.4 cu. ft.

I don't know if that machine is a true combo, though, Malcolm.  I think it's just a washer that can also dry a small load.  Their real combo holds much more. It's undoubtedly a gimmick.
