Difficult one - everyone will have their favourite pop-top and it's usually (but not always! ) the one they chose.
One thing to consider is whether you want/need to be able to leave bedding in the pop-top when it's closed - such roofs are sometimes, unkindly referred to as upturned bath-tubs - or whether you want/need the roof to be unobtrusive and inconspicuous (at least to the uninitiated) - a so-called "stealth" roof. Each has pros & cons, but I've yet to find a roof that satisfies both requirements.
Another thing to consider is who will be sleeping in the pop-top. Young children will probably be fine with a rigid bedboard and SIM, whereas older teens and adults would probably want/need the additional comfort afforded by a slatted bedboard or a bedboard incorporating a Froli spring system.
Also consider whether you want/need a bi-fold bedboard. Roofs with these afford a lot more headroom at the back of the van (when raised) than those with a standard single-hinged bedboard.
Finally, the price. Pop-tops can cost anywhere between £2k to nearer £9k, so your budget will influence your choice of roof.
