Component can be nearly as good, differences will be HDMI distance, and quality cable can be had easier and in most cases much cheaper...
Its Easier to route than Component, Can eliminate the Need for SEPARATE AUdio cables, and almost especially in todays world most of the components you will buy in the future will have better upscalling and or format options passing over the HDMI vs. Component.
So is it important, well its WAY easier, and yes in the end due to other availability and ergonomic issues will be better quality minimally 95% of the time.
