I enjoy both, personally. There's nothing quite like the experience of waiting in line at 4 in the morning to catch a good deal, lol! Although, I haven't done that in years. There haven't been any sales in the past years that were all that great to me, personally, and it's because of this reason I prefer Cyber Monday, or any online retailer's Black Friday/Cyber Monday sale. They usually are better and you can enjoy shopping at home. Hard to beat the convenience really.
That and even though it's "Cyber Monday", many websites do their own Black Friday or extend Black Friday to Cyber Monday where the two prime days are discounted with the weekend having a couple specials and such. It all depends on the website if they do one, the other, or something else entirely. Regardless, it's fun, hectic, and exciting even if it can get ridiculous, ha ha.
