I prefers clear MH lamps where you can see the arctube and the arc inside clearly.

I agree . I also have a coated lamp in my RAB Area Light JR . I initially had a clear in it but the pattern had WAY too many "hot spots" for my liking . I changed to the coated version and the area is nice and evenly lit now with no more "hot spots" I use clear when optical control is required (my Wide-lite) or something with a nicely patterned refractor .

Unless I have a reason to go with diffused, I generally prefer clear.  Works out well since they're by far the most common.

For me, I prefer retrofit quartz and ceramic metal halide retrofit lamps for mercury vapor fixtures sold in Japan the best.

Coated MH lamps are suitable for high bay and low bay fixtures, where they burns vertical.

I prefer clear, especially for places like my garage. All of my Metal Halides in my garage are using clear 50w lamps in those wallpacks. However, in situations where there may be hotspots, I prefer coated. Case in point, the Ceramic Metal Halide PAR38's that I'm using in my bathroom. All of those are clear, and their bright beams are lighting only one portion of the ceiling, not all around... so the rest of the ceiling in the bathroom isn't getting much light. Still looks nice, but it would look much nicer if the light spread apart more evenly. This would be the case if they were coated, and I may have a plan for that in the near future. Overall though, I definitely prefer clear Metal Halide. Coated Metal Halides lamps are awesome too though.
