I'm sure modern glass cockpits are much better than steam gages, but maybe there are some things like altitude, airspeed and vertical speed that might be better presented by a gage.
I would like to point out, that "better" has different modes of comparison.
Price? Cost of ownership? Reliability? Ease of maintenance? Intelligibility?
More easily integrated into the instrument panel? More rapidly assimilated?
ETC.
It is all a tradeoff. The issue is how to cover the maximum number of bases, and still give the crew what they need in the worst case they may face.
A mix of old style (steam gage) and new instruments (digital) can best do this.
