"Best" is a judgment call.  I'll offer one approach--extending
the Text class--but I wouldn't go so far as to call it "best."

[This is for 2.x.  No promises for 3.0.]

// The corressponding interface file should #import <appkit/Text.h>

#import <stdarg.h>
#import <streams/streams.h>

@implementation Text(PutSomethingCuteHere)

// Like setText:, but appends.  I recommend messaging
// scrollSelToVisible to the Text object afterwards, or placing
// one before the return.
- appendText:(const char *)aString
{
    int e;

    if ((e=[self textLength])<=0) [self setText:aString];
    else [[self setSel:e:e] replaceSel:aString];
    return self;
}

// For even more fun, we can build a printf: method upon
// appendText:.  Since all parameters after the format
// string are optional as far as Objective-C is concerned,
// delimit them with commas instead of colons.  Extend
// with NXRegisterPrintfProc() for even more flexibility!
- printf:(const char *)format,...
{
    NXStream *s;
    char *streambuf;
    int len, maxlen;
    va_list ap;

    va_start(ap, format);
    s=NXOpenMemory(NULL,0,NX_WRITEONLY);
    NXVPrintf(s, format, ap);
    (void)NXPutc(s, '\0');
    NXFlush(s);
    NXGetMemoryBuffer(s, &streambuf, &len, &maxlen);
    [self appendText:streambuf];
    NXCloseMemory(s, NX_FREEBUFFER);      
    va_end(ap);
}
