If you are looking for the smaller form factor the Dell Pro Max Micro FCM2250 is the right one for you. It is smaller than the Dell Pro 5 Micro P5M1260 and will fit more easily under your desk.
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 5 Micro P5M1260 as it is running a newer generation CPU. This is not to say that Dell Pro Max Micro FCM2250 is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
Both models have have equal amount of ram slots (2 RAM). Usually two RAM slots are more than enough for most cases. However, the count should be taken into account when planning how much and what combination of RAM you are going to need for your system.
The Dell Pro 5 Micro P5M1260 is using the faster 7200 MT/s RAM. The Dell Pro Max Micro FCM2250 is slower by supporting RAM speeds of up to 6400 MT/s. In addition, you will be able to install the same amount of RAM in both models, and most probably 64 GB of RAM will be enough for most people. However, if you will be needing more RAM, make sure to check other desktop models too.
Ports
In total the Dell Pro Max Micro FCM2250 has 8 USB ports. The Dell Pro 5 Micro P5M1260 is inferior in this regard and packs 7 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. It's great that both of the models have USB 3.1 ports which will allow you to exchange data with your peripherals at up to 10Gb/s. But if you need maximum connectivity, go with the Dell Pro Max Micro FCM2250 as it has 5 USB3.1 ports (the Dell Pro 5 Micro P5M1260 has 1).
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the Dell Pro Max Micro FCM2250 comes with 3 ports, while the Dell Pro 5 Micro P5M1260 has only 1. If you are planning to use multiple monitors, the Dell Pro Max Micro FCM2250 is the better choice.
The Dell Pro 5 Micro P5M1260 comes with an HDMI port, while the Dell Pro Max Micro FCM2250 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 0 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 5 Micro P5M1260 has 1 M.2 slots while the Dell Pro Max Micro FCM2250 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 Pro 5 Micro P5M1260 comes with a decent 100 Watt PSU, but the Dell Pro Max Micro FCM2250 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.
