If I am limited to the two scents that you discussed, I would, without a doubt, choose M by Puredistance.
However, you mentioned using the fragrance as a "signature scent", and, in that regard, try:
A Taste of Heaven by By Kilian - Upon application, one is treated to an invigorating and herbal, lavender accord. The fresh and clean lavender commingles with the pungent, medicinal bitterness of wormwood. An aldehyde-like effervescence can be sensed as the accord percolates and drifts to the heart. Here, in the middle, florals infuse and transform the lavender. Orange blossom, with its fruity sweetness, a sweet rose, as well as bourbon geranium, with its flowery and sweetly green facets, usurp the lavender. The lavender takes on a more floral slant. A hint of saltiness flutters about. Segueing to the mellow base, the woody resins of amber interplay with the vanillic, nutty and somehwat spicy aspects of tonka bean. A more camphoraceous and slightly smoky lavender develops. A touch of powderiness presents. Plumes of foresty oakmoss as well as earthy patchouli appear here and there. A shower of bourbon vanilla imparts its woody and aromatic facets. The fascinating blending of the foregoing leads to a resplendent drydown. This all-season, well-blended, and masculine composition can prove to be very versatile. Wonderfully, this somewhat classy scent has very good projection, a 2-foot scent cloud, and longevity, about 10 hours.
