Metering is an important tool in any engineer's toolkit and its importance is very often underestimated. Most DAWs do not provide VU meters and RMS metering which are in my opinion more useful when mixing audio as they are much closer to the way the human ear hears sound.
Most people who started out learning recording on a DAW would have little experience with other types of meters except peak meters. Peak metering is usually the default type of metering in most DAWs but some do allow you to switch to RMS metering. Peak metering is the most common in DAWs as peak metering is used to check for clipping. However, peak metering is not the way the human ear reacts to sound. Peak metering usually causes excessively loud recordings and can cause problems when mixing. If you have not used any other type of metering, download mvMeter to do some reading and experimenting with mixing with different types of metering. You will realise that you will get much better mixes as your gain structure will be improved as you're working in the sweet spot of most plugins and equipment.
