Preferred analyzer for library size/library quality

[MiSeqUser2020]

Hello! I am new to the world of NGS and am curious about the preferred instrument for checking library quality. The ones that seem most popular are Agilent Bioanalyzer, Fragment Analyzer, and Tape Station.

We currently use the Nextera DNA Flex Library Prep kit. We use the Qubit for quantification and assume 600bp as our average library size.

One more important alternative is the Perkin Elmer Labchip GX Touch.
They all work and differ in the resolution, throughput, reagent costs and setup effort.
