Well one of the things that is making me lean toward HOE is the preview below. One of things I want are controls that are as simple and easy as possible. I don't want to be frustrated by complex controls.

There’s a “focus” type of mode called “Ace Kills” that let you take down an enemy with a one-shot kill. First, you have to keep the enemy in your sights without firing your weapon—this will negate the powering-up of the special move—and fill the circular bar. Once it hits red, you can activate the mode, but if you can hold it longer and fully charge the bar, you can set yourself up for some bigger combined chain kills, taking out multiple bogies with one charge. Once you activate it, the world slows down and certain points on the enemy craft are highlighted to show you what can be shot for effect. On fighters, that includes the fuel tank and engine as one-shot kills. On fighters and larger planes, such as bombers, you can target the pilot for a one-shot kill, but you can also target the gunners on a plane, effectively silencing them.
The plane physics and controls for flying are easy, almost to a fault. The Left Stick is your basic flight control, enabling you to climb and dive and bank in any direction you need to. The rudder controls are built in to this, so there’s no need to control the finer points of steering—nor is there any possibility to. The Right Stick controls your throttle when flicked up and down, but also banks you without steering when pointed left or right. Controls like these are less about re-creating the realities of propeller-driven flight and more about making your plane do anything you want it to do in the air. It controls more like a TIE Fighter than a Spitfire. It is practically impossible to stall a plane in Heroes Over Europe, and crashing only happens when you get shot down or point your plane directly at something hard like the ground.
Anyway there will be reviews out for BOP before HOE is released in the US(since the game releases in Europe on Sept 4th). It will come down to what the reviewers say about who has the best controls, the best arcade mode, the length, and depth of the single player campaign, and the replayability of the single player campaign. Those are the 4 things I will base my decision on.
