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 490 G1 Microtower as it is running a newer generation CPU. This is not to say that Acer Veriton L4620g is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory

Additionally, if you will be needing a lot of RAM, better go for the HP ProDesk 490 G1 Microtower as it has the ability to run 32 GB of RAM. The Acer Veriton L4620g can do a bit less at max 8 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the HP ProDesk 490 G1 Microtower has 10 USB ports. The Acer Veriton L4620g is inferior in this regard and packs 8 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.
Unfortunately, only the Acer Veriton L4620g has a DisplayPort. The HP ProDesk 490 G1 Microtower does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.
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 ports are placed on the system board and it is where you connect your HDD, SSD and Optical Disk Drives. More SATA slots will allow you to have more drives running at the same time. In this regard the HP ProDesk 490 G1 Microtower is better equipped as it comes with 4 SATA slot(s), while the Acer Veriton L4620g has 1 slot(s).
M.2 SSD interface allows you to transfer data with higher speeds compared to the old SATA interface. Unfortunately, neither the HP ProDesk 490 G1 Microtower, nor the Acer Veriton L4620g 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 Acer Veriton L4620g comes with a decent 135 Watt PSU, but the HP ProDesk 490 G1 Microtower has a more powerful one rated at 300 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.
