Double for close in age, iCandy peach or bugaboo donkey?

[NotReadyForThisX2]

Ds will only be 13 months when Dc2 arrives. I used a sling sometimes with Ds but honestly liked to be able to put him in the pram sometimes rather than always hold/carry him. So thinking will definitely need a double.

We have the iCandy peach for Ds which can convert to double, but I'm not sure I like one under the other. Looking at the bugaboo donkey but it looks huge. Dp thinks we stick with what we've got as it won't be often used as a double anyway and obviously cheaper as we have it already. But I'm just not sure.
Anyone had either? Or any other suggestions? I want a carry cot for the baby so not a stroller type double.

No problem with storage at home, good size porch area for it to go in. Don't have the biggest car myself (currently polo, but thinking of upgrading ready for Dc2) but I'll be walking if I take the pram anyway and for family days out Dp's car is bigger.

I have the donkey with 2 year gap. It's mainly used in single mode but I like that I can take either the pushchair seat or pram out of the boot and shove on. Also use a buggy board or sling.

Positives about donkey:
Versatile, can take out in different modes depending
Seats/pram can face both ways (I really like having my little baby facing me in the pram)
Really well made

Cons:
It is a tank, no getting around that some places it doesn't fit also it isn't the easiest to store
The seats aren't huge so my big 2.5 year old is barely in the straps with his coat on (I believe the new version is better for this)
The front wheel gets a wobble on when you walk fast (also improved on the newer version apparently)

With a 13 month gap I'd definitely want a double as unlikely to be walking long distance for quite a while. (If you don't walk much then less of a problem)

Do you have or can you pick up second hand the bits that make your icandy into a double? If yes then I'd suggest using what you have got and go over to the donkey if it doesn't work for you.

If I was having my time again with a 2 year gap I wouldn't of bought the donkey but made do with the single. It would of ment I would of un-velcroed the pram/seat to swap them back and forth. With a 13 month gap I'd of bought a double as realistically you've got at least a year/18 month when you'll need one.
