I think the greatest heritage lantern has to be the Sugg Arc. These are used in Edinburgh and look fantastic on the Sugg-made repro cast iron columns. Many of the original columns have had their 90w SOX lanterns replaced with teardrops, namely DW Windsor Strands. I must admit the Strand is not a bad looking lantern, but they just don't look right on the centenarian Mackenzie and Falkirk columns.
The best looking teardrop lantern in my opinion is the Sugg Rochester, and bizzarely the bigger the lantern the better it looks. The smallest Rochester looks to be most realistic in size to the originals, the ones in the centre of Shrewsbury look fantastic. the next best teardrop would probably be DW Windsor Strand. The Urbis Albany is by far the ugliest, from its fat canopy to its exaggerated "U" bowl.
But Urbis heritage installations can look good. Here are some in my hometown of Bury St Edmunds.
