As said, it really depends on what you want to do, a torch that offers a great beam for close up work like reading isn't necessarily going to have a good beam for running at night off-road.
Some things to consider when choosing a torch
Beam pattern
A torch with a more flood type beam will be great for closer work, but won't be good for viewing anything further away
Beam Quality
A lot of the alpkit, Petzl torches i've tried have terrible beams.
They might look ok to someone coming from say a Maglite, but compared to decent modern torches their beams are terrible.
Most have dark lines or artifacts, this makes any work you do very tiring.
For close work like say reading a book you have to keep moving your head so the bit you want to see isn't in a dark area, with night hiking it's even worse as these artifacts hide rocks and roots that can cause you to trip
Tint
Another nail in the coffin for the Petzl, alpkit lights is their tint.
Might sound daft, but a white or even worse blue tint to the light will tire your eyes and blow out any detail.
A light with a darker tint (around CCT 4400k) will give a far far better rendition of colours, you'll be able to differentiate between say rocks and dust covered roots, you'll be able to see foliage better as greens will pop out more.
For someone not having had much experience with torches it's easy to brush this aside, it really does make a real world difference though
Battery type
Are you doing multi-day trips to remote areas?
If so those button type batteries might be difficult to find
AA or AAA lights seem great, but how many stores are there around where you intend to use the light?
Plus it'll inevitably be dark, will these stores even be open?
Again sound trivial, but if you have to start taking extra batteries these lightweight torches don't start to make as much sense any more.
I've got hundreds of toches these days, that run on everything from tint button sized batteries through to 12v car batteries, by far the most useful size is 18650
It's a fair old outlay to buy the batteries and charger and like all batteries you do need to take care.
The capacity for size/weight is fantastic though, plus they put out enough power to light really bright torches.
Comfort
I do a lot of night running and hiking, that super lightweight strap might seem great in the shop, after 15 mins on your noggin though it'll feel like some ones trying to garrotte your head in half.
So a decent strap is essential if you're planning to wear it for more than 10 mins at a time
Weight also comes into this, a heavy torch will bounce around and tire you a lot quicker.
I've got a old Petzl that has 4 x AA batteries in a case at the back of the strap, it's nicely balanced but a right sweat box when running.
So the strap and the torches weight need to be taken into consideration
Price
You might find all the above that suit you but only in a $6000 custom torch, so finding something that suits your pocket is also important
I'm a bit or a torch nerd and have bough hundreds of torches over the years, some were a waste of money, so these considerations are from mistakes i've made so hopefully you don't have to.
As i say i've got a fair few torches to choose from, the one that gets used on 99% of outdoors runs/hikes/trips is my
Zebralight H600w
Beam pattern is fantastic for night running/hiking, it has enough flood to illuminate a fireroad path from side to side, yet has enough of a throw to illuminate 50 meters in front easily enough
Beam quality is fantastic, no artefacts
Tint is a CCT of 4400k, so it brings out greens really well.
Where i run there are a lot of tree roots, this is made worse by the fact that it's very very dusty here, so these roots are covered in a thin film of rock coloured grime and dust.
The tint allows me to spot the slightly different shade of tree roots.
This is important as a wet tree root offers a LOT less underfoot friction than a wet rock
It uses a 18650 battery, my favourite
Comfortable to wear, i've often nodded off to sleep wearing it.
The newer version also have a 3rd over the head strap which gives a very secure fit, even when running
