I always used to use the first style and hated the second style. But at work we're using the second style and guess what, I got used to it within minutes and it makes absolutely no difference to me.

I generally prefer things like this:

if (something)
    ;
else
    ;
 
if (something)
{
    if (somethingElse)
      ;
   else
      ;
}
 
for (int i = 0; i < someNumber; i++)
{
   if (something)
   {
      if (somethingElse)
         ;
      else
         ;
   }
}

But I would never:

if (something) {
    ;
}

As going back and checking to ensure all the braces are in their correct spot would be tiresome. It's far easier to double check when they're all vertically lined up. (Though this is my own preference. If I got paid to do it in some weird way, then so be it).

I use both styles, but I am still consistent in it, although it may sound weird

I use the following only for class definitions, functions definitions, namespaces and these sorts of "top level" blocks:

void myFunction() 
{
   int a = 1;
}

And the following for if, for, while and other similar blocks:

if (a == b) {
   a++;
   b--;
}

And btw, for one-line if blocks i usually use this:

if (a == b)
   a++;
