I would suspect VOR would be least affected as they only transmit, the VHF receiver being in the aircraft. The aircraft receiver may receive interference which could reduce VOR range? Regardless, VOR would be first to recover if affected.Solar flares can affect all radio frequencies so VOR, ADF & ILS can also malfunction. In theory a really large Coronal Mass Ejection (CME) could disrupt all electronic communications on earth. If this was to happen almost all of our electrical systems, electronic gadgets, and all our global communications systems would fail. This would cause complete chaos due to our reliance on all of these things. This happened in 1859 when the Aurora Borealis could be seen from Cuba, compasses were rendered useless and telegraph systems failed. This was caused by a CME also known as a solar superstorm. How long it would last though is anyones guess.
whereas a GPS network of satellites would take time to recover.
