I can't really make a comparison to glass/metal toys because I woefully don't own any of those yet, but I do have the Ergonomic One Finger, so I can give you a basic impression.
The feeling: silky to the touch, and with a little more..."friction" I guess is the word, with insertion. Not bad, I mean, but it glides against the skin differently.
The weight: lighter than a silicone dildo
The cleaning: I use a tea tree oil soap and hot water. The wood is sealed, so supposedly you can use a regular antibacterial spray, but I don't fully trust the chemicals on the seal.
