Which is better if you like Macallan?

Of those three the Highland Park 12 most fits what you're seeking. Both of the others are fine whiskies. I like Cragganmore quite a bit, and I'm enjoying a Dalmore 12 as I write this, but neither are much peatier than the Macallan. The HP, while not very peaty, does have a little bit more peat smoke than the standard speyside. Along with some sherry and a little "island character" as well. Nice stuff.

wouldn't mind something a bit less smooth and with a bit of peat in it. Which of these three (or if there is something else I haven;t listed?) would be the best choice?

If it's a bit of peat you're interested in, try the new Isle of Jura Superstition, if it's available. I also like Clynelish a whole lot for a whisky with a light peat accent, but it's hard to find in the U.S. (thought the Signatory Clynelish 17 I got in Milwaukee three weeks ago is BOFFO--wonderfully subtle & complex, but also as succulently tasty as a mild-styled whisky can get--Clynelish has a very unique and delightful flavor, and this is a great expression). Also the Bowmore 12 really does qualify as being very enjoyable and distinctive but not overwhelming in the peat department just now, from my perspective

All these whiskies ARE still actually smooth. The peat just makes them uniquely flavorful.

All three are good and as Bart says the Highland Park will be more of a different experience than the Cragganmore or the Dalmore. Another with the "light peat" character would be Oban 14.
