Well IMO it depends for several reasons. Here's some things you may want to consider.
The SFAW10 is slightly higher priced. If you have a high ranged budget, get the AW210. If you want a higher current run, go for the AW210. If not move for the PHR. Most diodes in a specified color have a lifetime power curve, meaning that proportionally running the diode at currents compared to the manufacturer's rating will decrease the lifespan of the diode (mW). Since the AW210 has a larger range than the PHR, it may be better to go for it, since its much more flexible ranged than the PHR.
On the other hand, if you're going for a low-power build or budget, the PHR may slightly be the better choice, since its nicely priced, especially on modwerx (10$, AND ITS THE BARE DIODE! with uncut pins too.), and has a nice runtime as well as decent power to a certain degree, usually its best to run at most 130mA, gives you a maximum of around 90-100mW. AFAIK, it'll run for around 500-1000 hours. Maybe less.
You may also consider how well you solder and hand skills, as the PHR is a lot easier to work with, since its only the bare diode, whereas the AW210 must be harvested carefully from a sled. Do be aware that sledded diodes have noticeably shorter pins.
Too long? Go for the AW210 if you have the money.
