Solution
I would definitely recommend the larger. You would probably be overloading the smaller one. You are probably over 400W with the combo you described.

An UPS won't stop a lightning from killing components, neither will a surge protector. However, a surge protector is cheaper, though some data loss can occur if you for instance are writing to your drive, or something that is just bad timing. Most homes have protection against ligthning, and majority of well developed countries have 0 issues or have to turn off their electronics like in the old days. UPS is not 100% protection, a very common misconception. I suggest you do some research for what you really need. In the old days, a lightning could cause flamethrower like fire shooting out from the wall socket, do we see that today? I at least don't, thank god for that.

just general mishaps and electrical discharges that may damage components. The battery back up is nice as well though not sure if worth the extra money at the moment

List of 'mishaps and discharges' include frequency variations, harmonics, sags, RFI, polarity reversal, power factor, EMC/EMI, blackouts, high voltages, open neutral, floating ground, and surge. What protects from each? Nothing. Each anomaly requires separate solutions.

Most anomalies cause no hardware damage due to what has long been required inside a computer. For example, voltage can drop so low that incandescent bulbs dim to 40% intensity. Due to a robust design, even a voltage that low will not impede computer operation. If voltage drops lower, then a computer simply powers off without hardware or data damage. UPS has one function. To maintain power so that unsaved data can be saved. It does not and does not claim to do anything that protects hardware.

Reverse polarity, harmonics, frequency variation, etc are all made irrelevant by what is already inside every computer. You concern is one anomaly, that occurs maybe once every seven years, that can overwhelm protection inside computers and all other appliances. Nothing adjacent to an appliance protects from this rare and destructive anomaly.

A destructive surge can be hundreds of thousands of joules. How many joules does a power strip claim to absorb? A thousand? What happens when a destructive surge occurs? Protector parts must disconnect as fast as possible to avert catastrophic damage and a potential fire. Meanwhile that surge is left connected to attached appliances. Often that surge, that can destroy a protector, is too tiny to overwhelm protection in a computer. So what is that power strip protector doing?

View numbers for a UPS. It typically claims to absorb hundreds of joules - even less protection. So again, what is it doing when a surge that tiny is actually converted to low voltage and rock stable DC voltages to power its semiconductors.

For over 100 years, a completely different solution is miplemented so that even a surge called a direct lightning strike does not damage any appliance AND does not even harm the protector. This solution means a simple question is always answered. Where do hundreds of thousands of joules harmlessly dissipate? Outside in earth. Then nobody even knew a direct lightning strike or other surge even existed. Since protection means even the protector must not fail.

Every wire inside every incoming cable (TV, phone, AC electric, satellite dish, invisible dog fence) must connect an incoming surge low impedance (ie less than 10 feet) to single point earth ground. Otherwise that current is inside hunting for earth destructively via any household appliance - including your computer. Again, this is how it was done even 100 years ago.

A protector is only as effective as its earth ground. Neither that power strip nor UPS has a low impedance (ie less than 10 foot) connection to earth. Will not discuss it. And does not claim to protect from anomalies that typically cause damage.

If the computer needs protection, then so does everything in the house including a UPS.. Informed homeowners spend tens or 100 times less money for the proven 'whole house' solution to protect from an anomaly that typically causes hardware damage.
