I agree with C96 but it really depends on your usage of this compressor. For home workshop, I'm sure it will work just fine for you. If you want a compressor for an industrial application running 24/7, I'd stick with a unit that has a 1725 RPM motor.
Compressor manufacturers aren't stupid. To get maximum CFM out of a pump, you must have either large cubic inch cylinder bores or speed. Industrial rated pumps have large cubic inch cylinder bores but they turn at a slow speed using a 1725 RPM motor to obtain maximum service life. On the flip side, majority of big box store pumps have smaller cubic inch bores and turn at a faster speed using a more economical 3450 RPM motor.
Also, industrial rated compressors will incorporate a dedicated mag starter on the motor with thermal overload protection. The mag starter coil gets wired into the pressure switch contacts and the amperage draw across the electrical contacts of the pressure switch is less than an amp.
Whereas, big box store compressors incorporate a simple push button type reset thermostat mounted within the motor. In this case, the pressure switch electrical contacts see the full amperage rating of the motor every time the motor starts/stops.
Another topic most folks aren't aware of is that motors are capable of only so many start/stops per hour to achieve maximum service life (otherwise referred to as duty cycle). As you can see, A 4-pole motor (1725 RPM) is capable of twice as many starts per hour as a 2-pole motor (3450 RPM).

I had a IR 2475-N5 5HP 80 gallon vertical air compressor for 10 years and it was simply overkill for my small weekend warrior workshop projects. Sure....it looked cool sitting in the corner of the garage and every time it fired up, you could feel the exhilarating vibration through the concrete slab. This is an industrial rated compressor with 100% duty cycle meant to run 24/7/365. Unless you are running a tire shop where impact guns are buzzing car parts off all day long or you are using DA sanders and other pneumatic tools in a paint & body shop continuously you are most likely not going to get your money's worth in my opinion spending $2,000+ on an industrial rated compressor.
Prior to owning the IR, my father made an air compressor system for me. He took an industrial rated compressor out of a diesel truck used for the brake system. This compressor mounted off the engine and was driven off the crankshaft pulley. He modified the mounting bracket, mounted it to a simple 125 psi rated 12 gallon tank and installed a 1-1/2HP motor. I used it for 20+ years. The only downside was the tank was too small when I wanted to use an impact gun to buzz off lug nuts, etc. The compressor simply couldn't keep up as it was only rated for 4 or 5 CFM and the tank was simply too small. However, in hindsight, what I should have done is simply purchase a 175 psi rated 30 gallon tank. What you can't make up for in compressor CFM output, you can often make up for in use of a larger tank with higher psi rating. This would have more than satisfied my requirements.
