Power strips are limited in their use. They provide extra outlets for a single wall connection (of course). The only way they differentiate is whether or not they provide at least some protection for your equipment for surges or nearby lightning strikes. The downfall of all of them is is the power goes out, your computer drops like a rock.
That's where a UPS (Uninterruptible Power Supply) comes in. They have a battery backup, so even in the event of a brown out, or complete power outage, you have at least a few minutes of AC power being provided from the battery to power your computer down gracefully. Like, saving your files first instead of instantly losing them.
The battery also serves as a shock absorber for power surges. Most good UPS units come with a warranty of something like $10,000 if it fails to protect what you have plugged into it from being fried.
I have UPS units all over our house. On our computers, 65" OLED TV, and anything else I want to keep surges from destroying.
