If you've established a budget, the answer to that will lead at least halfway to the best decision for you, as most townhomes are priced higher than many condos. From a lifestyle standpoint, a townhome typically offers a bit more living space and considerably more privacy. A condo often offers more amenities, like swimming pool, fitness room, clubhouse, on-site management, etc., and not to mention, little maintenance. That low maintenance comes with monthly fees, however, as you incur costs associated with common area & exterior maintenance -- for things like lawn/landscaping, roofs, siding, garages, elevators, liability insurance, etc. Ultimately, some people are well-suited for condo living; others, not so much. Keep in mind, most TH communities will also have monthly association fees, though typically much less than in condo communities, as fewer amenities may be offered and fewer maintenance costs are shared with your neighbors.
I own property in this area myself, and would be happy to assist and guide you with your decision and search. Hope this helps!
