If the reflectors are not removed and the panels are 180° opposite, then there will be a combiner loss (up to 6 dB) plus uneven combining of undesired signals off the back of the half facing away from the source.

With the reflectors removed, the combiner loss is eliminated and there are lesser concerns about phase cancellation issues (assuming even illumination of all elements by the incoming signals). The downside is a loss of around 3 dB forward gain due to no reflector plus the increased possibility of multipath from signals reflected from behind the antenna.

I'd give a slight edge to "reflector-less" in this application.

since removing the reflectors is essentially a one-way trip if you don't have the tools or ability to reattach them.
If you have the tools to remove them, you certainly should be able to reattach them. Reflectors are easily reattached with standard #10 screws and nuts from your local hardware store.
