Size vs performance? I've personally have seen what Maglites can do to burglars, aggressive dogs, .....
I've used Mags as tools too, from leverage to a hammer. Their size is a benefit when needed.
Maglite leans toward reliability and useability. Sorry if they don't have 20 useless modes or don't fit in your pocket or have a bazillion lumens.
I'll include Kel-Lite. You'll sometimes find a 30-40 year old flashlight at a flea market or a yard sale, scratched up, dinged, inscriped with name or SN or ID or...... and it powers up with new batteries... says a lot for simplicity & good ol' Made in USA quality. Maglite, old KelLites, Brinkmann Legends.... will be still working when alien archaeologists dig them up.
I also own 20+ year old Maglites. Lets see how well all these so-called innovative and improved lights last. We already have seen import reliability with the number of threads on 'why doesn't my innovative improved cheaper import doesn't work right'. I know that I'm tired of replacing switches, fixing drivers, cleaning threads, fixing cold solder joints, improving contacts, stretching springs, adding little battery magnets...... The more import lights I buy, the more repair projects I have.
For the cost of the Maglite, I too could have several imported junk flashlights. But, I know that my Maglite will outlast any of them.
I, for one, wish that the 7D Maglite's come back.... caveman technology at its best!
I prefer flashlights that take normal batteries that are available everywhere and in bulk. The unrechargeable, when power is out, batteries are useless. The good ol' C and D flashlights make a great showing during every hurricane and snow storm induced power outage.
I don't have a problem with alkalines. If you use your flashlight, you'll end up replacing them before there is an issue. If not, make an effort to inspect or just replace batteries as needed. Stick with name brand locally bought alkalines. Too many alkaline 'name brand' clones and knock-offs sold online.
I certainly hope that Maglite doesn't go all gee-whiz gimmicky featured:

The Maglite also makes a great canvas for all the modders out there.
For those that demand more output or runtime, there are plenty of LED drop-ins and conversions available.
