I am doing a 6 inch cake with a 4.5 inch Sheriff's star on top. My question is will it be better to do a FBCT or just Gel transfer I fill in?

I like the FBCT's because they give you a flat decoration.

I have never used the gel, so I can't compare the two, but I LOVE FBCT !!

MODELING CHOCOLATE is my favorite! you can see most of my recent cakes all my decorations are modeling chocolate or a mix of mod choc and fondant. works Awsome and very very easy to carve

@ TexasSugar are they really flat? I just watched a tutorial on it since I have never done one and it looked raised almost with a 3D look to it. I have only used the gel transfer once and did not like how it came out nor the ease of its application. I have not had a need to do any transfers until now and since my cake and transfer was so small I did not want to overwhelm the cake. Maybe there is more than the Wilton technique to use the FBCT??
Thank you everyone for your useful answers and I would love to try the chocolate version
Thanks to all for replying
