I didn't think DOB was that bad, it's very rational like you can analyse situations really deeply but the thoughts aren't deeply meaningful at all. Acid is magical, DOB was not for me.
DOB is quite stimulating, somewhat speed-like making your head feel even more open and crystal sparkling clear than acid which is nice but doesn't stay interesting for 24-30 hours.
For me it was interesting as a curiosity to have tried (DOB) but did not feel wonderful - except for a couple of hours when I also got stoned and things got super-sparkly and every raindrop produced a rainbow, but apart from that I felt like a supercomputer that was bored to bits. Basically the visuals apart from being stoned on it were just colors getting more intense. It was nice but I got used to it fast enough.
Second time I did DOB I ate a lot of hash on it because the joint turned out so well the last time. I was completely overwhelmed, painful sensory overload and seeing multiple dimensions and cosmic spiritworlds that just didn't feel as awesome as it sounds. It felt fucked up and too much too fast and before the end I needed to abort with Valium to protect my grated nerves.
If you are looking for an acid-substitute don't bother, if you are looking for a whole new experience I don't see why you can't try it once or twice. Though there are many people who dislike it, and disliking something for that long a duration may not be worth it.
