Personally I like the look of R30's better than R40 lamps, so I put in the midsize. I also found that short neck halogens will screw up into the top of the trim so the lamps are not visible from accross the room. again, personal preference.
There are 10 types of people. Those who know binary, and those who don't.

Sometimes we need to use two 4" cans or 5" cans over the sink to get the correct spacing around the ceiling joists. Then we use the 6" in the rest of the ceiling. It is more important to be aware of the height of the bulb. In the Lightolier cans, the non-IC sit higher up in the can than the IC fixtures. So the spread of light is less with the non-IC. We also try to put the cans 22" off the wall so they will be out of the way of the cabinet crown moulding and be over the work space of the countertops. Sometimes we need to go with the 5" cans to accomplish this.

If you are cutting in existing the 6" gives you a bigger hole to drill & fish with. The 5" will fit in tighter places like between joists & pipes but some are 1/2" taller. Have not found a 4" remodel IC yet. So it's new construction 4" or clear away if any insulation.
As for looks I don't know if most customers could spot the difference between a 5" & 6" can. Smaller cans look better in smaller places. Depending on the can & trim but some 5" will take the same bulb as a 6".
The 5" & 4" cost me more so it is passed on to the customer.
