Mood: I took a look at both links, first to check whether they're Windows 10-compatible (both are) and to see what advantages either have over Windows Event Viewer. It looks to me like you also set set custom viewing parameters in EV's interface, no? The first choice has me wondering whether it's really a huge improvement over the Windows EV, even though Interface-wise, Windows EV is clunky, event descriptions go over my head most of the time(Ok almost all the time) and layout leaves something to be desired.
In "Advanced Options" the parameters can be set. If you filter the events (last 2 hours/last day) then it's faster than the Event Viewer, but without a filter it's painfully slow (or it's my slow PC ). To view all events it's maybe better to use the "original" Windows Event Viewer.
