Whether it's variable names, your brace style or indenting lengths, it doesn't matter if you think your way is the best, what matters is fitting in with the existing (shared) codebase so it's readable to everyone who has been working on it for the last 5 years.

Same is true for non-style things. If your project is 100K lines of 1998-era "C-with-classes" C++ code, your modern, templated, header-only, lambda-using work of art is going to cause more friction than it helps.
