It means AC appliances on battery backup runs hotter and less efficiently
The Costco model is good up to 900W this is only 810W.
Probably does not matter depending on your use case.
Personally I am going to spend the extra $15 and order from Costco. That way if I ever have issues in the future with it I'm more likely to be able to return/exchange it.

What does that means?
AC power look like waves. Battery power look like castle wall. Castle wall bad for some thing. UPS make castle wall look like waves. Some UPS do this better. Not important for most people.

it means nothing for any practical purposes. There is a lot of fakenews that you need pure sine wave output to protect "sensitive" electronics but people don't understand that all power supplies and anything plugged into an AC outlet is designed to operate with really awful and dirty AC power. Furthermore all products with AC power input have heavy filter at the input that negates any disadvantage of simulated sine way.
the fakenews started many years ago when computer power supplies with poorly implemented power factor correction would become confused, shut off or not work properly with simulated sine waves (as the PFC circuitry tracks the phase of the input to better match and time current consumption to improve the power factor). This isn't really an issue with modern power supply designs.

I'm not sure the term 'fakenews' applies. More accurately, it's dated information. While true that PFC power supplies did have problems, and those problems were avoided by using a PURE Sine Wave PS, current (A)ctive PFC power supplies no longer have this issue, at least in where 120v power is concerned.
See this thread on Corsair's own website, and the verbiage shared by the legendary Jonny Guru, the founding father of power supply reviews[hardforum.com]. Very cheaply made and/or systems running on 230v power can still have issues in certain circumstances.
The valuable electronics nowadays use switching power supplies, which have rectifiers to convert the AC to DC, then to high frequency AC, and then back to DC. This way the transformer is much smaller and have better control and efficiency.
Therefore it doesn't really matter if you have a simulated or true sine wave. Desktop PCs and TVs will be just fine with it. The easiest test is to measure the consumed energy of a device running with a true sine wave and simulated sine wave. If it is the same then there is no less efficiency because in order for a device to run hotter, part of the energy has to be converted to heat.
B&H is a great company to deal with.
This UPS is not the strongest one in that series so if you got a gaming PC like mine, you would want to go bigger. Most people will get by with the one in the OP. The AVR function is great too.

If it dont make no diff then why are they still sold with distinction and at diff price points? Cant be all marketing and must be some technical need?
the AC power produced by the inverter very closely matches an actual sine wave. In modified sine wave inverters, the polarity abruptly switches from positive to negative. When looking at the wave, it has a stair-step, square pattern, where the polarity is flipped back and forth. That choppy wave can negatively affect more delicate, sensitive equipment. If you have medical equipment you need to power, such as a CPAP machine, you won't be able to use a modified sine wave inverter. Additionally, in many cases, you'll hear a hum with devices attached to a modified sine wave inverter.If you have to compare pure sine wave and square wave(sine wave vs square wave), the simple answer is that pure sine wave are better than square wave in terms of safety, work efficiency, and compatibility.
It means this thread will now turn into a glob of peoples hunches, repeating what they heard someone else say, and tell you their version of what they believe are facts that might not be what happens in reality.

This is because it requires just a little bit more effort in terms electronic components but generates more profit margin for the manufacturer. There are still use cases where true sine wave is needed - AC motors, actuators, relays, etc.

You are working with a false premise. Yes they are more expensive, yes the electronics are more complicated, yes the specifications are better, but no it doesn't make any difference for any normal use case.

They do not return to last state if powered on pre outage
