No question, You want a GPSDO. Yes you can buy a Rb or a high-end OCXO but neither of these is connected to any kind of standard and will need to be calibrated to be of use. The GPS serves as a "standard" and you need that before the other options.
The next question is "which GPSDO?" For most people that would be a Thunderbolt but the prices are going up on those. Then you will need a good antenna installation.
