We have a front loader.
I like it because it seems to be more gentle on our clothing. The old top loader used to make our jeans stylish (beat up looking) in no time at all. Also, it has a sanitize feature which comes in handy for my husband's scrubs (he's an RN) and our hockey gear.
The things I don't care for (though I do still like the machine) are: it's too low so gets hard on the back (get pedestals), loads take almost an hour for the regular cycle, though there is an express cycle that takes 20 minutes if I'm in a pinch and it requires monthly maintenance if you want to keep it from developing a funk. The maintenance only takes 10 minutes but it's something to take into consideration. It's recommended you leave the washer door open when not in use to prevent the funk but ours is in a hallway.
Our old dryer works fine still so we kept it. Part of me wishes we'd bought the matching dryer so I could stack them but a bigger part of me prefers to have the extra $750 in our vacation fund.
When I first got it, I wished we'd kept with a top loader. Now I like it. I like the extra space on top for folding clothes and really, I'm mostly grateful that I don't have to use a washboard or beat our clothes on rocks anymore.
