Reviews, not so much. When you are putting together a professional workstation you do need to look at processor and memory requirements, and drive type and size.
So a big difference if you say you need 16GB of memory vs 128GB of memory. Or need a 6 core CPU vs a 24 core CPU.
When it comes to professional work, value is more or less your budget. A budge oriented workstation, is the best you can get with the money you have.
All that said, for an OEM machine I like Dell Precision towers myself. Anything is basically possible. From truly ludicrous amounts of memory, multiple GPUs, NVMe storage, RAID arrays, multiple CPUs with high core counts, etc. All on an upgradeable platform. You can get similar things from HP and Lenovo.
