I don't care for the grounding strip in our applications. The only thing it has going for it is that it's inexpensive. I very much like an insulated strip which is more compatible with our wire gauges. Compared to the cost of the layout, each appropriate strip we may purchase is less cost than one piece of track. I think it's important not to focus on one favorable aspect of a choice, but to think more broadly about all the aspects including safety, ease of use, appropriate for the purpose and compatible with the associated parts, etc.
