I had a mismatched washer and dryer set for a very long time (like 15 years) and one day the washer quit working completely. Like no power was getting to it at all anymore right in the middle of a load. The dryer was on it's last leg.
We went and looked at washers and I had always wanted a front loader and a lovely blue Samsung set was on sale that week. Well, we got both and for the first time in my life I had a matched set!
As far as odor, I had researched a lot and so I never close the washer door unless it is running. I don't leave clothes sitting in the drum wet, I get them in the dryer as quickly as possible. I have had my set exactly 4 years, as we bought them about the last week of April. I love them! The only problem I have had is my kids would slam the washer door shut, which really should be closed gently and they they broke the latch, but we ordered a new part and my husband put it in and we instructed the kids that the next one who slammed the door would be buying the new part and no problems. They broke the latch about 15 months after we got it and we have not had any problems since then with either one.
I am 5 foot 2, so reaching into the bottom of a traditional washer is a challenge for me, I love the front loaders and they don't bother my back because I am already short.
I hope you enjoy whatever you decided to get. I love my front loaders and would very much love to get another one if I need a new set, but hopefully I am good for another 10 years or more.
