I have a TC LV and Bk LN 16610, both are with BK right now getting frankensteined but as soon as I get them back I'll do a side by side comparison.
For the price you can't beat a TC however I wouldn't count-out a BK if you really want a LN asap and don't mind the higher cost. The BK TW bezel assembly is more gen looking than TC. Some will try to argue that the TC LV shallow-teeth bezel is based off a Y series (mark I) however the TC LV dial is a mark VI so the parts don't match. BK sub case dimensions is not accurate, however incorrect crown height is not something 99.9% of people will notice.
If time is not so much an issue I would possibly get a TC sub, throw on a Correctime bezel assembly, and just source a LN dial. Cost for all parts should come out to about the same as a BK 16610LN.
