Hi,
Any underslung bottle cages will be experiencing forces back to front.
You are going to need an additional retention strap et cetera if you're not going to lose to the bottle every time you hit a bump in the road.
Even with a strap of sum description bottle will still ride up out of the cage.
Metal cages find Score plastic bottles quite badly.
If I have to use metal cages then they normally have plastic inserts to be kinder to the bottle.

I have different systems for my three different bottles.
1 A Bikebuddy for a 1 litre Trangia fuel bottle under the downwtube. Hanging bottles exert quite a bit more force on a cage, and the BIkebuddy is a more robust system. Also, it is invisible when I don't take a fuel bottle, with just the little pegs for a neater look. The system allows you to fit a quite large bottle because you only have to move the bottle about half an inch to remove it. It has proved very secure, even on truly rough roads.
2 A Bikebuddy on the seat tube for a 1 litre stainless thermos. The thermos is a bit of an odd shape (tapering to the top) but that is not a problem with a BIkebuddy. Again, when not in use the looks are very clean with just the litle pegs on the seat tube. And again, the Bikebuddy systems allows you to use a bigger bottle than you could otherwise fit.
3 A Velo Orange Mojave cage on top of the downtube, to fit the largest possible bottle. I did a tour in Germany in the summer of 2018, and it was terribly hot and I was struggling to carry enough water. This is not a very small frame, but even so I had to look carefully for the best fitting bottle. And I wanted a stainless bottle rather than a plastic one, for cooler and better tasting water. The large Kleen Kanteen bottle is nice and light but with its long neck it would not fit. I bought a Nalgene 32 oz bottle with an On the Fly top. It fits very precisely in the Mojave cage. This bottle has a rather more efficient shape with a short neck. When full, the bottle is a bit big and heavy to use while riding, so I stop when I want to drink. The top is OK, but no more than that, but unfortunately there are no other sportscaps for this wide neck bottle. All in all I am quite pleased with the combination of these three bottles. They do the job, and they look quite good on my elegant custom steel m-gineering tourer.

My underslung Ti King cage doesn't do any of this, even after thousands of miles on dirt roads. I've used a strap in the past with cheap bottle cages, but the King doesn't need one. Would perhaps be different with very large bottles, but I don't use them.

On my tourer a Sigg fuel bottle sits in its proprietary cage below the down tube. There's a mention of fragility above and the cage has needed some reinforcement.

Cages can be conveniently repositioned with the Topeak adaptor "Alt Position Cage Mount". We now have three of these: simple but effective. One needed a hole to be converted to a slot.

Ditto, using the King Stainless version and Arundel stainless, no scoring of the bottles.
Now my ancient REG spring locking cage, they really chew on the bottle.

Hi,
If the under slung is not going to be accessed more than once a day / not accessed enough to cause bother and you don't have to slide the bottle out but has a clamp of some sort OK.

But my under slung bottles I access whilst on the bike mostly, I pull out the down tube one and hold in my teeth and access the under slung, place this in downtube then reseat the empty into the underslung position...several times a day. And off course I also recycle the seat tube one, that's on the tourer (3) skip trainers (2) down and underslung (mtb older type with only down tube bosses), the road bike only had a down tube bosses so its underslung attatchments for bottle rack, with the normal downtube bosses, frame bag and frame pump restrict the seat tube.

If you are carrying heavy metal and fluid / tool kit then I can see it would probably need clamping as it would move around on bumpy terrain.
For me I need bottle space as I normally ride three hours without stopping, bottle an hour then stop for refill.
