These are some of the relaxed geometry/sportive frames out there; if you HAVE to judge without test riding them judge it by stack and reach; its a metric that is not hard to understand and evaluate. You can measure the stack and reach of your current bike using a spirit level and compare it with the ones listed above (and more).
Generally feeling the need of upright frame means you are lacking core strength require to keep the upper body upright without pressure/weight on your hands but thats a different subject.
