Processor
Usually the newer the generation of the CPU, the better the performance and efficiency is. If your budget allows it, you should go with the HP ProDesk 600 G2 Microtower as it is running a newer generation CPU. This is not to say that Lenovo ThinkCentre M73 Small is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory

The HP ProDesk 600 G2 Microtower is using the faster 2133 MT/s RAM. The Lenovo ThinkCentre M73 Small is slower by supporting RAM speeds of up to 1600 MT/s. Additionally, if you will be needing a lot of RAM, better go for the HP ProDesk 600 G2 Microtower as it has the ability to run 64 GB of RAM. The Lenovo ThinkCentre M73 Small can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the HP ProDesk 600 G2 Microtower has 10 USB ports. The Lenovo ThinkCentre M73 Small is inferior in this regard and packs 6 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals, like external Solid State Drive, you will need to look elsewhere.
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the HP ProDesk 600 G2 Microtower comes with 2 ports, while the Lenovo ThinkCentre M73 Small has only 1. If you are planning to use multiple monitors, the HP ProDesk 600 G2 Microtower is the better choice.
None of the models has an HDMI port. If your monitor supports only the HDMI interface, you will need to buy an adapter. Such adapters are cheap so nothing to worry about.
SATA slots are located on the motherboard and it is where SSD, HDD and Optical Disk Drives are connected. Each of the two models being compared have 3 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.
M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the HP ProDesk 600 G2 Microtower, nor the Lenovo ThinkCentre M73 Small has one. However, you can still use a SATA SSD drive which should give you satisfactory performance.
Make sure that the available M.2 slot supports the PCIe (also called NVMe) interface. This is important as there are M.2 slots which support only the inferior SATA III interface. For comparison, the SATA III interface has max speeds of 6Gb/s, while the PCIe 3.0 x4 will support speeds up to 32Gb/s!
Power Supply
Having a Power Supply Unit with high power rating is important, if you are going to use components which require extra power. The Lenovo ThinkCentre M73 Small comes with a decent 240 Watt PSU, but the HP ProDesk 600 G2 Microtower has a more powerful one rated at 280 Watts. Choosing either one depends on your specific requirements and use case. Also don't forget that some models might have more than one PSU option - try to always get the most powerful one, especially if you plan to upgrade to a powerful GPU.
