Is there any fighter in the world that can equal the F-35 other than the F-22?
Short answer: When it is IOC, no.
“Is there any fighter in the world that can equal the F-35 other than the F-22?”
I’m sure there are some fighter jocks on this board that could answer the question from an operational perspective, but as with many things, the answer is “it depends”.
An F-16 with an experienced pilot could probably do well against it in many scenarios.
An F-15E will easily outperform it for strike missions.
There is a tendency, when talking about new aircraft, for the Air Force to minimize the capability of existing airframes, and the ability to upgrade them to provide similar capabilities to new aircraft. This has to be done to justify new aircraft costs - so take estimates of “X times more effective than Y airframe” with a grain of salt.
