IMHO It's unfair to compare a twist type, which are usually quite robust,
with the sort of holder that comes with a cheap buzz box.
Referring to my previous post I'm binning a 400a twist in favour of a 400a croc.
Like for like. (see pics stolen from the bay)

That's the crocodile type I had on an old oil cooled and it had various angles not just 90° and 45°. If you want you could file your own groove to tailor it to your needs and the spring tension is good. It's not something I had thought about really I just used whatever was available when working in the foundry.

My guess, welder runs rod in holder A with right hand (presuming he's not a southpaw) until rod almost gone, transferring it into left hand as monkey passes rod holder B with fresh rod into right hand (a sort of "nurse, forceps" kind of moment); welder applies rod in holder B to job, withdrawing A from work at same time and handing to monkey to refresh rod.
Thus is the arc never broken.

Never thought much about this. All my welders came with 'crocs' and the few times I used a twist, it seemed a bit awkward. But then I use sub 200amp kit, and perhaps there is a difference with big amps? Plus, I like the different angles with croc. Use the 30deg as my prefered daily weld.
Noticed: the OP suggested big amp types use crocs... Puzzled, as I assumed the higher clamping loads were better for big amps with twist.

Very interesting replies from everyone here, I'm going to be looking at rod holders soon, and I'll see what there is and what kind of prices they are. Mine is the yellow twisty one in the picture a couple of posts back. It has served me well, but changing rods sometimes is a little pesky as the rod will get jammed up the side of the jaw and simply will not just drop out even with a good tap, I have to use pliers to prise it out.
Well it isn't exactly a major financial undertaking to buy an electrode holder, even if you launch the boat and go for a genuine Myking.
One thing you might check which could save you a bit of hassle is whether it clamps the bare end of the cable with an Allen key arrangement or requires a cable lug which fixes with a bolt. It would be a pain to be messing about cutting a lug off or in want of a lug if you didn't expect it.
My croc clip holder uses a lug and the screw down uses the Allen key clamping arrangement.

Mines got a bare wire setup on my current torch use an allen key to release the cable. I know its not a major financial decision, I just dont want to buy something that I will not use.

Twist grip type with the handle cut back to about 3-4" long. Fits in the palm of your hand and you can get into some tight spaces. Good for welding pipes when there in the rack.

Thats an idea! Why didn't I think of that? I find that the length of the handle can sometimes be a bit of a problem, like you say when you are pressed for room. I'll give that a go, thanks!

If you can get some make up the last 4 or 5 feet of your welding lead with superflex cable. Really does make a diffrence.

Its only a buzzbox, don't really feel like pimping it! hahaha the cable is rather light already, as its only a 130 amp unit.

Twist for me mostly, although not like the yellow one. But use what is available. Croc's can be better for out of position work as you don't need to try to bend the rod, quite a lot don't like it and half the flux falls off.
This is my preferred type.

That's what the murex at work has nice slim unit and can do a few different angles including almost straight out of end. Now just need my welds to look like tino's!
pritty much, usally hold the fresh rod near the ark for a moment to get the end of it hot so it's much more eager to take up the ark.
also found it to be a really good way to find the thermal cut out or let the magic smoke out of the cheep boxes
