I disagree. I think in the end, the ring of invisibility is far superior. With the blindfold, nobody is invisible to you within range. With the ring, you're invisible to everyone, no matter how close or far away they are. I think the ring has a lot more uses than the blindfold, such as stealing treasure, or anything else (no matter the lighting conditions), escape, evasion, and long range attacks, to name a few.
Blindfold+deaper darkness= invisiblity that doesn't go down.
The blindfold stops anyone from sneaking up close to you. It stops all gaze attacks and some spells.
I see the ring of invis being better for defense and the blindfold better for offense. If you have a couple daylights, and 3-4 dispels, I can easily have that many deeper-darkness items in an extra-dimesional space (Helet's Handy Haversack works perfectly) so they are not dispelled. If you daylight that coin, I can toss it and draw another. If you daylight the ground, I can back up and still get my darkness. You still can't see me, but I can see you.
One last reminder: blindsight goes through most illusions. What kind of bonus is that? Illusioned pit traps will never be a problem again, nor walls. Trick me with any image spell - no. All in all, I would opt for blindsight for far more characters than I would for the ring of invis, especially if blindsight only costs 9k.
