Electrolux vs Whirlpool Washer/Dryer - which one to buy?

Costco seems to be running a good sale and I can get a set for either of these at around ~$1K which seems like a good deal to me.

They're all within the same price range, so I'd rather just pick the best one out of the three. I need a gas dryer, and they will be in a stacked set up. What is important to me is reliability first, then performance/features. It's going to be installed in my garage, so I could care less about noise levels.

The specific models I am considering are:

Electrolux ELTG7600AW (all in one laundry tower - is this going to be harder to repair if something should happen?)

Whirlpool (two different pairs on sale):
WFW4720RW | WGD4720RW (between the whirlpools, based on what I've researched so far, leaning towards this due to people saying the accessible drain filter is a great thing)
WFW6605MW | WGD6605MW (slightly bigger washer, but I personally don't need the extra capacity)

Any opinions on which one I should get? And for the drain filter access concerns - I'm trying to look at the Electrolux, don't really see an accessible drain filter either, is it that important? I don't think I've ever cleaned or accessed my previous drain filter (GE) if that matters.
