When it comes to gun stats, burst fire is usually a handicap of sorts designed to allow a gun really high accuracy without sacraficing clip capacity or damage output or any of the other things typical "accurate" guns lose. The M16 in call of duty games being a great example, that gun hits like a truck but has near flawless accuracy, and aside from a somewhat slow fire rate, its lack of full auto allowed for much higher total stats.
So yeah, burst fire is rarely a boon, its usually a tradeoff to create a very well rounded gun.
As far as if I like it..no. If for no other reason than I have this bad tendency to fire and miss the target by like a frikkin half inch, causing me to get owned before it lets me fire again.
While full auto lets me sort of sweep if I miss the initial few shots.
Edit: and yeah, the guy above me has a point, ammo is scarce in real military situations, so full auto is used primarily for supression, most guns are semi-auto.
