Ok folks, would like to share my brief impressions after spending some time with few quality mechanical pencils which are considered as an upgrade to the RM3.00 Pilot pencils sold in your neighbourhood stationery stores.

Firstly, as seen here in this thread, it is down to personal preference as the pencil which I feel is comfortable may be considered as uncomfortable to another person. For instance, Synical found the Uni Kuru Toga Roulette to be uncomfortable but I find it fairly comfortable.
Comfort and looks are based on personal preference which is subjective. However, some aspects of the pencil such as the technology incorporated into it and the writing experience are objective so most people would be able to come to an agreement.
Ok straight to the point. To me, if you want something that is truly special and different, the Uni Kuru Toga would be it. After comparing all the pencils which include the Zebra Delguard with its patented unbreakable lead technology, the Uni Kuru Toga still remains as the best mechanical pencil to me in terms of writing experience. As mentioned earlier, the rotating mechanism inside the Uni Kuru Toga really works in keeping the lines sharp all the time as the lead is constantly rotated by the pencil. All other pencils which include Staedtler and Zebra Delguard write the same as the cheap Pilot, or any other pencil for that matter. The lines don't stay consistent and sharp as they get smeared and go wider after you write for a while. As a result of the thicker or wider lines due to the excessive slanted tip of the lead, the shade also gets lighter and not as dark.
As for the unbreakable lead technology of the Zebra Delguard, personally I don't find it unique as I don't usually break the leads with all pencils which I write on these days, even the cheap Pilot. Perhaps useful for people who are heavy handed who exert a lot of force on the pencil when writing on paper. I only break the leads when writing on REALLY cheap mechanical pencils, maybe those costing RM0.50 or 1.00 a piece. That was way back in time when I was in school.
In summary, for me the Uni Kuru Toga is the best pencil for writing as it maintains the thickness of the lines. With other pencils. If you want to maintain the thickness of the lines, you need to rotate the pencil 90 to 180 degrees with your fingers. Otherwise, you just continue to write with thicker and smeared lines ie. Instead of 0.5mm, you get 0.7 or 0.8mm thick lines, and with lighter shade.
Uni Kuru Toga ADVANCE vs. ROULETTEBetween the Advance and Roulette, I find that there is no difference in the function as both pencils maintain the line thickness very well. One is not better than the other although the rotation speed in the ADVANCE is 2 times that in the ROULETTE. Perhaps other more experienced users may be able to explain the advantage of the higher rotation speed in the Advance model. To me, there is no difference.
However there is a difference where the Roulette with slower rotation speed writes slightly smoother on the paper when compared to Advance. Just a small difference. It is likely the higher rotation speed which causes the lead to rotate quicker ultimately induces more friction on the paper when the lead is rotating at higher speed.
ComfortAll pencils feel comfortable to me but if I were to rank them in order, from most comfortable to least comfortable as follows;
1. Zebra Delguard and Uni Kuru Toga Advance (tie)
2. Staedtler 925 35 07 and Uni Kuru Toga Roulette (tie)
The larger diameter and smooth grip area of the Zebra Delguard and Uni Kuru Toga Advance contributed to the added comfort. The smaller diameter and textured surface of the grip area of both Staedtler and Uni Kuru Toga Roulette brought down the comfort levels a little, but overall they are still fairly comfortable to write on. No complaints.
SUMMARY
I may sound like a broken record by now, but I would surely recommend the Uni Kuru Toga if you want a different and better writing experience from your RM1.00 to 3.00+ mechanical pencils found in your common stationery stores. I feel the basic models instead of the Roulette will be good enough. Perhaps the rubber grip or Gel grip version of the Uni Kuru Toga.
Zebra Delguard and Staedtler don't really feel too special in terms of writing experience but they are well made and look pretty good (metal body, beautiful design etc.). But in terms of comfort and particularly heavy handed users, the Zebra Delguard will be a good choice.
