In addition to what Amir has measured on this site (M16, F35, C25), Revel spin data are available here:
Objective loudspeaker measurement data - how to find it, how to interpret it, how to choose speakers based on the data.

F36 looks particularly good.
Erin measured 2 Arendal speakers in the lower line:

They also look good.
Arendal's published measurements are too smoothed to make any determination from them.
Both brands/lines look to be up to the task, so other factors may influence your choice. Where do you live, what finishes do you prefer, does your room and seating position benefit from the back tilt, etc.
I have heard the Revel F36 and walked away impressed enough to think I may have "wasted" a bit of money on my F206. I have not heard any Arendals, but I hope to.
