None of which provide any protection vs. INPUT power surges, those are all on the OUTPUT of the power supply protecting it from abnormal OUTPUT conditions and offering some protection to the gear connected to the PS for power from some failures OF the power supply.

 Personally, I generally go for APC or Square D equipment (all my UPSs happen to be APC, all my breaker panels for decades have been Square D) but there's plenty of good surge protector makers out there.

 DO keep in mind that some forms of surge protection DEGRADE every time they have to soak a hit - and some hits are small enough your equipment never notices, but it still does some degradation of the protector.
 Multi-stage surge protection tends to reduce this issue a lot by using one or more early stage(s) that don't degrade (but offers less protection) to limit the surge input to the stages that DO degrade, but even those aren't immune to the issue.
