Have done a few items with SendCutSend and nothing but good experiences.
Thinner stock I have found to be smooth except at the start / end points of the laser cut.
I have found that thicker parts can come with quite rough edges.
This flange base is 6061 aluminum in 0.375" / 9.5mm was very rough on the outer edges (not the holes/center hole though). This is after quite a bit of sanding and wire wheeling. Sufficient for my needs but would have taken a lot more sanding and grinding to make smooth.
