Jaenak,
As I said, grips are an individual choice. The choice is dependent on how the pistol will be used, but more importantly, how the shooter grips the gun and the anatomy of the individual's hand.
I personally tend to eschew frontstrap checkering. I want my hand to slide into place quickly. My two handed grip is very much an isometric style Chapman grip most of the time. Thus, I tend to want traction on the sides of the grip frame. Checkered grips work for me. FWIW I also tend to prefer a flat serrated mainspring housing, a long trigger and a Ed Brown grip safety. Not all of my 1911s have this combination, but most of the ones I have personally smithed for myself do. On my carry 1911s I go with checkering on the grip for the grip qualities, and rubber for the durability. Guns that get carried lead a tough life.
A fellow with a different shooting style might prefer smooth grips and a checkered frontstrap. Another guy might find he shoots best with checkered everything. Some want coarse checkering, others fine. Some only want serrations, others want smooth. What is important is to learn to grip the pistol properly, and have it fit your hand. If you grip it correctly, and it fits your hand, all the traction modifications are really superfulous.
The nice thing about the 1911 is the ability to almost infinitely alter the grip frame. If you think you need traction on the front strap, put on some skateboard tape and try it out before having it checkered or stippled. Buy some inexpensive checkered or smooth grips before you settle on a style different than what you have. Try a checkered and a serrated, flat, wedge, and arched mainspring housing. Swap parts with another fellow, and you both get to try new stuff.
The 1911 grip frame is almost infinitely variable to fit almost any hand, almost any need. There is no right or wrong, no better or best. There is only what works best for you that you learn from trying different things and shooting the gun. I think perhaps that is why so many folks love the old thing. They can fit it exactly to their needs.
