The real strength of the 1hbh is that it has the potential for significantly more peak brute force than the 2hbh. A longer lever arm, a faster racket head speed. You will get more topspin and more pace. You sacrifice the control and stability of the two-hander for spin and POWER. That is why you should love the 1hbh, not because of what it looks like.
2HBH is easier to learn by kids; 1-handed BH is quite difficult for kids to learn.
There are more body parts involved in 1HBH, than 2HBH.
1HBH looks more elegant to most people imo.
Topspin with 2HBH is quite natural; with 1HBH it is also possible.
Easier to drive with 2HBH, also with 1HBH.
1HBH have natural slice, 2HBH must learn it.
Wide, out of reach balls, are difficult to return with 2HBH because of limitation of reach. 1 handed BH is good for such conditions such as wide balls, slice approach shots followed by 1-handed BH volley.
With 1 handed BH could be hit with topspin as well as underspin. With 2HBH you
always hit with topspin, slice is almost impossible with two hands on the handle.
With 1 handed BH you have more economy of movement i.e. movement is easier with 1hand BH; with 2 hands on the handle, movement is quite cumbersome. Example: Handcuff your both hands and sprint for 10 seconds (measure the distance). Now, open the handcuffs and sprint for 10 seconds (measure the distance). You will discover that you were more speedier without handcuffs!
In certain situations, such as wide return of serve, or you have been pulled wide on your forehand side, and then there is a wide ball to your backhand side, it is almost impossible to return with 2HBH. In such situation, single handed BH comes in handy!
1HBH requires more strength, time, and experience to master than the 2HBH.
If you are a step slower, you tend to hit more slices with 1HBH than topspin drives that require more time and space to execute.
Should we say then that the 2HBH is more powerful because there are two hands on the handle? I know with 1handed BH you have more upper body rotation and with this the distance over which the racket will travel to hit the ball is more, thus more power! But then this added advantage is even out by 2HBH because additional power comes from the left hand as well.
Because of limitation of reach, the 2HBH player must be fast on his feet to overcome this deficiency.
Because the 1HBH employs more upper body rotation, more loop-type backswing, the single handed BH player must be quick on his feet to create time and space to hit his backhands with authority. If this player is a bit slower, he will end up hitting his backhands with slices!
You can see that both backhands have advantages and disadvantages.
Look at Safin, his double handed BH is the most powerful and cleanest shot you will ever see.
Look at Kuerten, his single handed BH is the most devastating shot you will ever see!
