A few questions about replacing our clothes washing machine

Yesterday, while doing a regular load of laundry, the glass on the front of our washer completely shattered. My current theory is that it was a temperature thing. The washer is in our unheated basement, and I wash my clothes on hot (I know, but it helps with my allergies!), so I’m wondering if the repeated heating and cooling stressed the glass over time.

Anyway, the washer is about 7 years old, and almost certainly in need of replacement (small shards of glass got in the drum and internal mechanisms because it kept turning for a bit before we ran down to our basement and turned it off).

I have three main questions:

1. We’re potentially looking at an all-in-one washer + dryer machine, but have read mixed reviews. Anyone have hands on experience with these and can speak to them? We do have a working dryer currently, but it is late in its life.

2. To avoid the same problem we had with this one, we’re looking at top-loaders instead of front-loaders, but I’ve heard they have balancing issues. Anyone have experience with these?

3. Regardless of configuration, does anyone have specific model recommendations/avoids?
