The reason I didn't go for the toddler seat that clips on the front is firstly, my brand of jogger pram couldn't take one (a weight and stability issue) so I would have to get a new pram anyway, and then secondly, my dd still sleeps in the pram, and i felt that she'd would be better in the strider plus as they seat is full height and both recline, whereas a toddler seat doesn't. Also, I thought that it was fine in terms of space whilst my 2nd was a tiny baby, but as soon as they would get to an age where they wanted to sit up, it would be pretty squashy for the baby, especially as they got bigger. Saying that, it depends if you think your DD will still be pram riding or not. I went for the strider plus as I felt both would be comfy, especially for long walks.
