I don't own either of these particular light / laser combos, but I have owned both Streamlight and Olight weapon-mounted lights.
Streamlight is going to provide you with better off-the-shelf or quick-ship holster availability from holster manufacturers. I like Olight's QD lever system, but being able to choose from a wider variety of light-bearing holsters might help alleviate the need to remove the light so often in the first place.
Because of this holster issue, it makes a difference how and where you plan to use the gun. If for example you are using it only for home defense and transporting it to the range, then you don't need an IWB holster that fits your light. If you are planning to concealed carry it, then you will be thinking about getting a good holster that is comfortable and conceals well with the light, and/or you will be removing the light regularly to put your gun in a regular holster. In my case, I do both. I will carry in a light-bearing IWB when I am traveling or if I am out at night. Around my local area during the day, I remove the light and carry in a smaller and more comfortable IWB holster. I'm talking about carrying a P-07 and comparing between the PL-Mini 2 and TLR-7 so all of these things are smaller and lighter than a SP-01 with a full-sized light / laser combo, but the holster support issues are pretty similar. The TLR-2 is going to have a lot more holster support than the Baldr Pro.
