Some biners are better for certain things. One example might be using an oval carabiner to rack wires. Some prefer racking with other types such as pear or D. Ovals can also be used to make back-up rappel devices and i am sure they are great for many other things. I just don't use them. IMO these are the most useless. Of course, many would disagree. The bent gates are for ease of clipping into. The wire gates are to safeguard against flutter. To demonstrate this, take a regular carabiner and smack it against your hand. You should hear it open. Now take a wire gate biner and do the same thing. Quiet. Gates opening is the number one cause of biner failure. Hence this design. I'm sure others will comment more on what else other carabiners are good for but there is a quick answer for you.

If you aid/big wall climb, you'll quickly discover the advantages of oval biners in a number of situations.

-Key lock ovals for racking stopper (kong), -Wire gates for alpine draws and cams(neutrienos) -Solid streight gate one end and a solid bent gate on the other for my sport draws(spirits). -Key nose lockers for sport anchors(positron), -large HMS for belaying (willams). -Large pacificOmega wire gates that are easy to use with gloves for ice climbing, but too big for rockclimbing.

Yes, they are very useful for aid as well. They can be flipped around easy, they don't get in the way of other carabiners while clipped, they weight in the center nicely and I'm sure there is much more great about them... oh they're cheaper! Sweet. But, i dislike their strength and weight in comparison to other stronger/lighter carabiners and the gate space being so minimal when opened annoys me. They have their use, like every piece of gear, don't get me wrong. I just prefer others while not aiding. I haven't done any big walls yet (unfortunately) but i am sure they are useful there, also.

many climbers act like girls in shopping malls and they think few ounces of weight difference and fancy biner look will make them fly faster while eating fat food at local in-out burger forgetting about added weight .. while biner manufactures are making money marking biner that are very much offer same beefy rating

Everybody knows it's not the biners that make you climb faster...

It's the lycra

I contend that the lycra is the reason you have no climbing partner in this photograph.

Oval- Good for pulley or Ascenders as will hang straight down D -really strong as force Goes down spine Pear/HMS -good for a itailian hitch belay as wont jam in corner. Also if you need Lots of space( eg clip in point on anchor for several people, or gear.)
