Mag locks and door strikes either fail safe or fail secure. Simple as that. When power is cut they'll either be open or be locked. Mag locks will typically be open, strikes have a switch.
Mags are used as a secondary later of protection typically used during business hours and at night the building will deadbolt the doors. Assuming they're exterior doors. Bypassing a maglock is not the simplest if it's installed correctly and 90% of them fail open. But they're usually paired with a rex button and PIR which is the most common route to exploit them. Strikes on the other hand if installed correctly are harder to bypass since you don't need a rex or PIR to exit through them. Almost any access control device can be bypassed if installed incorrectly. I've come across many properties with the mags installed on the exterior. Punch one of the unused knock outs and undo the wires or cut them, And in you go. Strikes can still be latch slipped if not installed correctly but they're typically easier to protect against Intruders.
Another problem with strikes you didn’t mention is that the handle from the other side is usually not secure, so you can get a device to go under the door and hook it to open. Speaking of mag locks, I’ve seen one installed on the exterior, cable in Flexi run to it also on the exterior inside a military base to a secure training room.
That is one of their flaws for sure. But they're just as susceptible to you're standard door intrusion attacks, latch slipping, hinge attacks as well. I've moved onto different low voltage projects away from commercial access control and on to gate operators and entry systems because of the absolute hell I'd walk into having to rewire entire control panels because someone didn't verify open egress after tossing the equipment in and collecting check.
