For ceiling lights I agree with BAS fluorescent have around 95 lumen per watt, and with HF units last around same time, cheaper to install and much cheaper to renew.
However for a garage we often want light lower down, the fluorescent is easy to break, using tubes made in plastic does have some advantages as already said we often need the spread of light but not the amount of light so we get away with lower output tubes, but for the garage we have to consider the strobe effect, using HF fluorescent or LED with a switch mode LED is OK but simple capactors used to control current there is a strobe effect problem, so one has to be careful selecting, replacements for the fluorscent tube are in the main switch mode they need to be to get 100 lumen per watt to be better than the fluorescent they replace.
However with stand alone LED lamps, it is not unusual to find cheap and nasty capactor current regulaton, when I looked for an example to show how many lamps do not give 100 lumen per watt so likely have cheap capactor regulation and so a problem with strobe effect I found many simply don't tell you how many lumen and watts even when the law requires it.
