Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.
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 Dell Pro Slim Plus QBS1250 as it is running a newer generation CPU. This is not to say that Dell OptiPlex SFF 7010 2023 is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Dell Pro Slim Plus QBS1250 has 4 RAM slots while the Dell OptiPlex SFF 7010 2023 has only 2 slot(s). This is not something to worry about. Just make sure you take it into consideration when planning how much RAM you are going to use.
The Dell Pro Slim Plus QBS1250 is using the faster 5600 MT/s RAM. The Dell OptiPlex SFF 7010 2023 is slower by supporting RAM speeds of up to 3200 MT/s. Additionally, if you will be needing a lot of RAM, better go for the Dell Pro Slim Plus QBS1250 as it has the ability to run 128 GB of RAM. The Dell OptiPlex SFF 7010 2023 can do a bit less at max 64 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the Dell Pro Slim Plus QBS1250 has 10 USB ports. The Dell OptiPlex SFF 7010 2023 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. What is nice about the Dell Pro Slim Plus QBS1250, is that it has 2 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell OptiPlex SFF 7010 2023 has no such port, thus restricting your transfer speeds significantly. For people who want to use external drives on regular basis, this might be an issue.
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell Pro Slim Plus QBS1250 comes with 3 ports, while the Dell OptiPlex SFF 7010 2023 has only 2. If you are planning to use multiple monitors, the Dell Pro Slim Plus QBS1250 is the better choice.
The Dell OptiPlex SFF 7010 2023 comes with an HDMI port, while the Dell Pro Slim Plus QBS1250 does not support the interface. Of course missing HDMI port is something that can be easily fixed with a good adapter (e.g. DisplayPort to HDMI).
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 2 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.
An M.2 SSD can be several times faster than a SATA one. Thus, we are happy to see that both models support the M.2 interface. However, the Dell Pro Slim Plus QBS1250 has 1 M.2 slots while the Dell OptiPlex SFF 7010 2023 comes with just 1.
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 Dell OptiPlex SFF 7010 2023 comes with a decent 300 Watt PSU, but the Dell Pro Slim Plus QBS1250 has a more powerful one rated at 360 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.
