I have raised Finnsheep for about 10 years. Their wool is a long staple wool that is good for hand spinning (though I don't spin, I sell it). The meat has a delicate flavor, not that overwhelming "lamby" taste that store bought lamb does. Our ewes are pretty friendly, but the rams and wethers are very friendly and like to follow us around. If you just want one for a pet and wool, I would consider a wether.
One note about Finns, though, is that they act a little more "goat like" than the Suffolks I used to have. Especially when it comes to grazing. My Finns prefer to eat shrubs, weeds and flowers rather than plain grass. They are also a little bit more of escape artists and climbers than the Suffolks.
