If I change a conventional (horizontal) radiator for a tall vertical one of
the same BTU / Wattage, will there be any differences in the heating
effect?

Not really, but the heated air won't follow the same path which may be
awkward. Because they're taller and narrower, the patch of ceiling
above the radiator will be smaller and hotter which may or may not matter.

I have a couple of 3kW verticals - big buggers - in the kitchen and
hallway and they both work well, but kitchen one is higher output than
the conventional radiator it replaced.

They're also a lot more expensive and heavier, but you do regain a lot
of dead wall. They look better IMO too.

I have one about to be fitted in a narrow space in my bathroom - like the
look of it so much I was thinking of changing a couple in the lounge - as
you say - you regain some wall

Most of the heat input will be delivered directly to a thin band of very
hot air close to the ceiling which will eventually fill the room.

Well they do actually radiate some heat too. More so if they are
'modern' and black.

To look effective they need to be installed with hidden pipework,
so replacing an existing rad is not straightforward.

They radiate a only tiny amount and any paint colour apart from polished
metal is "black" in the thermal IR band. Most of the heat will be
convective and make the ceiling a really nice place to levitate too.

You could consider a kick space heater and liberate wall space
that way.
A bit of fan background noise but pretty efficient.
