I got my SVI Ti Tiki a few months ago after a LONG wait.
It is truly an amazing gun! I carry it quite often and have just been amazed by it.
I have Sig Grade customs from Ted Yost, Brian Bilby, J Harrison, Marc from Gemini and I am sure a few others I can't even think of right now. I can't say any of them are truly better than the other. Some are nicer in certain areas but when you get to that level it's just another game. I also have a couple from Nighthawk and Wilson Combat which are just as marvelous as the full blown customs by they guys above. The advantage with SVI or any individual smith is you get to talk to the guy actually making it, you get to tell him what you like, what you want, bounce ideas off each other etc and you know that the $ is going in his pocket so he has more in it than a typical employee (not saying Nighthawk or Wilson guys are anything typical! They are amazing). You can't go wrong with any of the names in this thread, you have to find what you can afford and what you like most and who you feel most comfortable working with.
That being said I am debating a Bill Wilson Carry II (with the rail) in 9 mm to potentially use as my EDC. I love the size, I love that it has the rail (nothing comparable from Nighthawk does, sure they will likely build you one but it will cost a lot more than the Wilson since the Wilson is a regular run gun and adding a rail to the compact Nighthawks will be a full custom and a longer wait). I have never owned a 1911 in 9 mm but with age Im warming up to the idea of it for carry.
Long and short of it more or less ANY of those guns will outshoot us and are worthy of owning. Buy what you LOVE!
Here are some pics of the Tiki (SVI took them, I wish my pics were this good LOL). I hope it is ok I posted these here, if not please delete and just let me know.
ETA SORRY! Just did a search for Wilson here and replied, now I see I bought back an OLD post!
