Both seem overly pricey to me.
I'd be more interested in the shape of them for the job.
I use some run of the mill modern Stanley's for paring, I find the steel decent for that,
but the translucent plastic handles can become loose on them, which might be of annoyance to some, doesn't seem like the easiest thing to fix.
These are cranked and more comfortable for a parer, being flat is nice for that one.
My Tesco ones wouldn't be flattenable being so concave/hollow along the length,
so even more tendency to dive into the cut behind the line,
i.e a lot more so than a flattened chisel does this, so I use the parers afterwards.
These Tesco cheapies have a handle in-line with the chisel, so better for whacking.
I reckon I'd sooner a bellied chisel for this use, as it's more steerable out of the cut, but I don't see a great need really.
My 2 cents, I wouldn't do without having both types, and I'd look for some options say in homebase bargain bucket, or discount pound shop for say 3 quid a chisel.
Might be easier to get a parer which has flat faces/back than a bellied set of chisels,
but I doubt you could buy premium tools with such a profile.
Regarding this last part, the steerability aspect is obviously favourable for a lesser steel, as most damage occurs from sinking a chisel too deeply,
or without having somewhere for the waste to go.
I suppose the only time where these Tesco ones really shine is really heavy paring on an angle,
they would be quick for cutting the 45 deg bed of a wooden plane, an odd task in the general scheme of things, and obviously still would need cleaning after with something a bit more refined afterwards.
