tl;dr: Your monitors, router, etc. won't care about simulated vs. pure sine wave, but your computer's power supply might.
Longer explanation - electronics experts, please do correct any inaccuracies in this because I do want to fully understand it, but right now am just confident enough to potentially be completely misunderstanding things.
AC power comes in alternating waves of highs and lows. Typical power runs in a sine wave (even up, then down, then up, then down) patterns. Pure sine wave battery backups will also generate this same up, down, up, down pattern at precise intervals.
A device that is simulated sine wave will approximate this pattern, but it won't be as precise. This is a far cheaper alternative for devices that don't really care about sine waves.
The issue comes in with a PFC power supply like most computers have. The power protection circuits on the power supply will not always like the simulated sine wave output from a non pure sine wave device, and if that circuit is tripped in the power supply, your PC will power off to attempt to protect your PCs internal parts from being fried. This is typically a good thing since if you weren't using a UPS, a non sine pattern could indicate a short, surge, or other power fault that could very well fry your PCs components.
Now, the real caveat here, is that it is kind of up in the air whether your PC's specific power supply will be sensitive enough to care about the differences this UPS will produce. Some will, and some will not.. From my experience it isn't even always consistent between power supplies of the same model.

As I understand, batteries (charged by the grid) will emit a pure sin wave i.e. "cleaner"and safer for electronics and appliances due to minimal fluctuations in amps or voltage. However, it seems @greyson76 is implying that perhaps this is simply simply a pass-through device that will not use the batterys properties but only use battery power in the event of a power outage.
I would love to hear more about this topic from anyone whom is in the biz or has knowledge.

Not really a deal, it comes up everytime there is a staple coupon.
A pure sine wave UPS at $130 will be hot which hasn't happened for over a year.
Thank you
