I got a Click recently, and mine unexpectedly came with all modes available... So with 8 modes to cycle through, I swapped in the reverse clicky switch. It's got a unique UI (for me anyway), and I found myself kind of working around the mode memory by switching it to moonlight before turning it off. For all that mode changing, I personally prefer reverse clicky. However, if it only had two modes programmed, I suppose forward vs. reverse, one isn't dramatically better than the other.
Anywho, I have the Quark tailcap tool (comes with extra boot covers and orings), so swapping the switch was a breeze. I believe that circlip (snap ring) pliers will also do the job quite well... But without the right tool, swapping switches would have been a bit more challenging. The switch retaining ring on my sample was pretty tight. As they say, YMMV.
