The Optec unit looks like a refractor focuser unit. The PDF is quite flat. The PDF has around 10mm of travel and the Optec 12.5mm.
FLI is a premium products company. Their gear is usually the best in class.
I am not familiar with Optec, perhaps they are in the same league but if it were my choice I would chose FLI as I have had only great experiences using FLI products so far. Also very good customer service and backup.
